​
invalid_native_app_id

Description: Invalid or missing native app identifier for mobile clients Common Causes:
  • Using wrong client ID in your application
  • Native app identifiers not configured in Privy dashboard
  • Using Expo Go without allowlisting host.exp.Exponent
  • Web clients accidentally sending privy-native-app-id header
Troubleshooting:
  • Verify client ID: Double-check that you’re using the correct client ID from your Privy dashboard
  • Configure app client: Ensure you have an app client configured in your Privy dashboard
    • For Expo Go development: Add host.exp.Exponent to your allowed application identifiers in the dashboard

​
invalid_origin

Description: The origin that your requests are coming from has not been allowlisted in your Privy dashboard Common Causes:
  • You are using an appClient (and therefore setting clientId in your PrivyProvider) that is overriding the allowed origins for your application.
  • You haven’t added the origin to your allowed origins in the dashboard.
  • Your request is coming from an iFrame whose parent origin is not allowlisted.
Troubleshooting:
  • If you are using an appClient:
    • Set the allowed origins for your application in the dashboard here.
  • If you are not using an appClient, you can set the allowed origins for your application in the dashboard here.
  • Make sure to add all parent origins of your application to the allowed origins list here.

​
linked_to_another_user

Description: There is a conflict between the current user and an existing user. Common Causes:
  • User previously signed up with Google/Apple OAuth using this email, then tries passwordless email login
  • User tries to update their linked_account to one that’s already taken
  • Importing users with duplicate linked_account
Use case:
  1. A user creates an account with one email ([email protected])
  2. This user links a different email via OAuth ([email protected])
  3. This user then tries to log in with the linked oauth account ([email protected]) using passwordless login, this will fail because this email is not associated with a passwordless login method.
Troubleshooting:
  • Enable login method transfer to allow users to migrate their accounts. Learn more here.
  • Make sure the user is using the correct email address for the login method they are trying to use.

​
failed_to_fetch_jwks_uri_document

Description: Failed to fetch JWKS URI document when configuring JWT authentication Common Causes:
  • Cloudflare or similar security measures blocking Privy from accessing your JWKS endpoint
  • JWKS endpoint not publicly accessible
  • Incorrect JWKS.json structure
  • Firewall or security rules restricting external access to your endpoint
Troubleshooting:
  • Check security configurations: Review your Cloudflare settings or other security configurations that might be blocking external access to your JWKS endpoint
  • Validate JWKS structure: Verify your JWKS.json follows the required structure:
{
  "keys": [
    {
      "kty": "RSA",
      "n": "your-n-value",
      "e": "AQAB",
      "alg": "RS256",
      "kid": "your-key-id",
      "use": "sig"
    }
  ]
}

​
Wallet proxy not initialized

Description: Privy was not able to initialize the wallet proxy to interact with embedded wallets. Common Causes:
  • The application’s origin is not allowlisted
  • The app is not waiting for Privy to reach the ready state
  • The app is not waiting for the wallet to be fully initialized before interacting with it
Troubleshooting:
  • Confirm that the origin is allowlisted in the dashboard here.
  • Ensure that you are waiting for ready here and potentially ready from useWallets here
