Resolution Steps: Check API Key Restrictions

• Verify if the key is restricted to specific APIs:
  1. Navigate to the API Key Management page in Google Cloud Console.
  2. Locate the API key being used and check if it is restricted to specific APIs. If the restriction includes discoveryengine.googleapis.com, ensure it is correctly configured.
  3. Remove unnecessary restrictions: If the key is restricted to unrelated IP addresses or applications, remove those restrictions.
• Enable the Discovery Engine API
  1. Go to the API & Services page in Google Cloud Console.
  2. Search for Discovery Engine API and ensure it is enabled.
