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
      => {
        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: "email-address",
  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 => 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

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
