4.2 - Privy App ID Error

If you encounter a Privy-related error, here are the solutions.

Problem: "Cannot initialize the Privy provider with an invalid Privy app ID"​

Symptoms:

  • Console error: Cannot initialize the Privy provider with an invalid Privy app ID
  • Application does not load properly
  • Wallet cannot connect

Solutions​

1. Check that VITE_PRIVY_APP_ID is defined​

Check that the VITE_PRIVY_APP_ID variable is defined in your .env file:

VITE_PRIVY_APP_ID=your_privy_app_id_here

2. Check that the ID matches your Privy application​

  1. Log in to Privy Dashboard
  2. Select your application
  3. Copy the App ID from the dashboard
  4. Verify it matches the one in your .env

3. Check the ID format​

The Privy App ID should have the following format:

  • Usually starts with cl (for new applications)
  • Example: clxxxxxxxxxxxxxxxxxxxxx

4. Restart the development server​

After modifying the .env file, restart your development server:

# Stop the server (Ctrl+C)
# Then restart it
pnpm dev

5. Check that the ID is not empty​

Make sure the ID is not empty or malformed.

6. Check PrivyProvider configuration​

In your WalletContext.tsx, verify that PrivyProvider uses the environment variable:

<PrivyProvider
  appId={import.meta.env.VITE_PRIVY_APP_ID}
  config={{
    // ... configuration
  }}
>

7. Check build errors​

If building for production, make sure environment variables are properly injected during the build (see the Environment Variables section).
