When to use this skill

Use this skill when you encounter:

• Sign in button does nothing
• User is authenticated but useConvexAuth() returns isAuthenticated: false
• ctx.auth.getUserIdentity() returns null
• Email or name fields are undefined in identity
• Admin access check returns false for valid admin users
• JWT validation errors
• OAuth callback redirect issues
• Environment variable configuration problems

Diagnostic checklist

Run through these checks in order:

1. Verify environment variables are set

Frontend (.env.local):

VITE_CONVEX_URL=https://your-deployment.convex.cloud
VITE_WORKOS_CLIENT_ID=client_01XXXXXXXXXXXXXXXXXX
VITE_WORKOS_REDIRECT_URI=http://localhost:5173/callback

Convex Dashboard:

• Navigate to Settings > Environment Variables
• Verify WORKOS_CLIENT_ID is set

2. Verify auth config is deployed

Run npx convex dev and look for "Convex functions ready!" message.

If you see an error about WORKOS_CLIENT_ID:

1. Follow the link in the error message
2. Paste your WorkOS Client ID
3. Save and wait for deployment

3. Check WorkOS Dashboard configuration

Redirect URIs:

• Must include http://localhost:5173/callback for local dev
• Must include production callback URL

CORS Origins:

• Must include http://localhost:5173 for local dev
• Must include production origin

JWT Template:

• Must include email claim (see Problem 2 below)

Common problems and solutions

Problem 1: Sign in button does nothing

Symptom: Clicking Sign In has no effect. No redirect to WorkOS.

Root cause: Using deprecated getSignInUrl() or incorrect event handler.

Solution: Use signIn() directly from the AuthKit hook:

import { useAuth } from "@workos-inc/authkit-react";

function SignInButton() {
  const { signIn } = useAuth();
  
  return (
    <button
      onClick={() => {
        localStorage.setItem("authReturnPath", window.location.pathname);
        signIn();
      }}
    >
      Sign In
    </button>
  );
}

Do not use:

• getSignInUrl() (deprecated)
• Manual URL construction
• Direct navigation to WorkOS URLs

Problem 2: Email is undefined in identity

Symptom: ctx.auth.getUserIdentity() returns user but identity.email is undefined.

Root cause: WorkOS JWT templates do not include email claim by default.

Solution: Configure JWT template in WorkOS Dashboard:

1. Go to WorkOS Dashboard > Authentication > JWT Templates
2. Edit the default template
3. Add claims:

{
  "email": "{{user.email}}",
  "name": "{{user.first_name}} {{user.last_name}}",
  "picture": "{{user.profile_picture_url}}"
}

4. Save and redeploy

Verification: After fix, identity should include:

{
  tokenIdentifier: "https://api.workos.com/user_management/client_xxx|user_yyy",
  subject: "user_yyy",
  issuer: "https://api.workos.com/user_management/client_xxx",
  email: "user@example.com",
  name: "User Name",
  pictureUrl: "https://..."
}

Problem 3: JWT validation fails intermittently

Symptom: Authentication works for some users but not others. "Invalid token" errors.

Root cause: Only one JWT provider configured. WorkOS issues JWTs from two issuers:

1. SSO: https://api.workos.com/
2. User Management: https://api.workos.com/user_management/{clientId}

Solution: Configure both providers in convex/auth.config.ts:

const clientId = process.env.WORKOS_CLIENT_ID;

export default {
  providers: [
    {
      type: "customJwt",
      issuer: "https://api.workos.com/",
      algorithm: "RS256",
      applicationID: clientId,
      jwks: `https://api.workos.com/sso/jwks/${clientId}`,
    },
    {
      type: "customJwt",
      issuer: `https://api.workos.com/user_management/${clientId}`,
      algorithm: "RS256",
      jwks: `https://api.workos.com/sso/jwks/${clientId}`,
    },
  ],
};

Run npx convex dev after changing this file.

Problem 4: Callback redirects before auth completes

Symptom: After login, user lands on page showing "not authenticated" briefly.

Root cause: Callback component redirects before AuthKit finishes token exchange.

Solution: Wait for AuthKit loading state:

function AuthCallback() {
  const { isLoading, user, signIn } = useAuth();
  const [authFailed, setAuthFailed] = useState(false);
  const hasAuthCode = useMemo(
    () => new URLSearchParams(window.location.search).has("code"),
    []
  );

  useEffect(() => {
    // Wait for AuthKit to finish
    if (isLoading) {
      return;
    }

    // Only redirect after session established
    if (user) {
      window.location.replace(returnPath);
      return;
    }

    // Auth code present but no user = exchange failed
    if (hasAuthCode) {
      setAuthFailed(true);
      return;
    }

    window.location.replace(returnPath);
  }, [hasAuthCode, isLoading, returnPath, user]);

  return (
    <div>
      {authFailed ? (
        <button onClick={() => signIn()}>Try Again</button>
      ) : (
        <div>Finishing sign in...</div>
      )}
    </div>
  );
}

Problem 5: useConvexAuth returns false after login

Symptom: User successfully logs in via WorkOS, but useConvexAuth() returns isAuthenticated: false.

Root cause: Backend not correctly configured to validate tokens.

Diagnostic steps:

1. Check convex/auth.config.ts exists and has both providers
2. Verify WORKOS_CLIENT_ID is set in Convex Dashboard
3. Run npx convex dev to deploy config
4. Check browser console for JWT validation errors

Common causes:

• Missing WORKOS_CLIENT_ID environment variable
• Only one JWT provider configured
• Auth config not deployed after changes

Problem 6: Admin check returns false for valid admin

Symptom: User with @yourdomain.com email shows as non-admin.

Root cause: Usually Problem 2 (email not in JWT claims).

Debugging:

// Add logging in your admin check
export const isAdmin = query({
  args: {},
  returns: v.boolean(),
  handler: async (ctx) => {
    const identity = await ctx.auth.getUserIdentity();
    console.log("Identity:", JSON.stringify(identity, null, 2));
    
    if (!identity) {
      console.log("No identity");
      return false;
    }
    
    const email = identity.email;
    console.log("Email:", email);
    
    if (!email) {
      console.log("No email in identity");
      return false;
    }
    
    return email.endsWith("@yourdomain.com");
  },
});

Check Convex Dashboard Logs for output.

Problem 7: Platform not authorized error

Symptom:

WorkOSPlatformNotAuthorized: Your WorkOS platform API key is not authorized 
to access this team.

Root cause: WorkOS workspace has been disconnected from Convex.

Solution: Reconnect or create new workspace:

npx convex integration workos disconnect-team
npx convex integration workos provision-team

Note: You may need a different email for the new WorkOS workspace.

Problem 8: Missing aud claim error

Symptom: Token validation fails with audience claim error.

Root cause: WorkOS JWTs may not include aud (audience) claim by default.

Solution: Check WorkOS Dashboard JWT configuration:

• Ensure audience claim is set to your Client ID
• Or configure Convex to not require audience validation

Debug logging

Frontend logging

function DebugAuth() {
  const { user, isLoading } = useAuth();
  const { isAuthenticated, isLoading: convexLoading } = useConvexAuth();
  
  console.log("AuthKit state:", { user, isLoading });
  console.log("Convex state:", { isAuthenticated, convexLoading });
  
  return null;
}

Backend logging

export const debugIdentity = query({
  args: {},
  returns: v.any(),
  handler: async (ctx) => {
    const identity = await ctx.auth.getUserIdentity();
    console.log("Full identity:", JSON.stringify(identity, null, 2));
    return identity;
  },
});

View logs in Convex Dashboard > Logs.

Environment variable troubleshooting

Verify Vite picks up env vars

// In your app, temporarily add:
console.log("VITE_WORKOS_CLIENT_ID:", import.meta.env.VITE_WORKOS_CLIENT_ID);
console.log("VITE_WORKOS_REDIRECT_URI:", import.meta.env.VITE_WORKOS_REDIRECT_URI);

If undefined:

1. Ensure variables start with VITE_
2. Restart dev server after changing .env.local
3. Verify .env.local is in project root

Verify Convex picks up env vars

Check Convex Dashboard > Settings > Environment Variables

If WORKOS_CLIENT_ID shows error in logs:

1. Click the link in the error
2. Set the value
3. Wait for redeployment

Production vs development

Different callback URLs

Development:

VITE_WORKOS_REDIRECT_URI=http://localhost:5173/callback

Netlify Production:

VITE_WORKOS_REDIRECT_URI=https://yourdomain.netlify.app/components/callback

Custom Domain Production:

VITE_WORKOS_REDIRECT_URI=https://yourdomain.com/callback

All callback URLs must be added to WorkOS Dashboard > Redirect URIs.

Different CORS origins

Add all to WorkOS Dashboard > Sessions > CORS:

• http://localhost:5173
• https://yourdomain.netlify.app
• https://yourdomain.com (if using custom domain)

Different Convex deployments

Set WORKOS_CLIENT_ID separately for:

• Development deployment
• Production deployment

Netlify specific issues

MIME type error on Netlify:

If you see Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "text/html":

1. Ensure netlify.toml exists with SPA redirect:

[[redirects]]
  from = "/*"
  to = "/index.html"
  status = 200

2. Ensure vite.config.ts uses base: "/" for Netlify hosting
3. Clear Netlify cache and redeploy

Callback not working on Netlify:

1. Verify redirect URI in .env.production matches what's in WorkOS Dashboard
2. Ensure the callback path includes any base path (e.g., /components/callback)
3. Check Netlify Functions logs for any errors

Quick fixes reference

Symptom	Quick fix
Sign in does nothing	Use signIn() not getSignInUrl()
Email undefined	Configure JWT template in WorkOS
Intermittent failures	Add both JWT providers
Callback timing	Wait for isLoading to be false
Admin check fails	Check email claim in JWT template
Platform error	Reconnect WorkOS workspace

When to escalate

If none of these solutions work:

1. Check Convex Discord for similar issues
2. Check WorkOS documentation updates
3. Review recent changes to auth config
4. Test with minimal reproduction
