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.

Troubleshooting: "Requested Entity Already Exists" Error When Saving Data Stores

Error: When saving site indexing, the following error message appears:

Failed to save sites
Requested entity already exists
Tracking number: <mix of English and numeric characters>

Root Cause: Conflicting URL patterns exist simultaneously in "Specify URL patterns to index":

example.com

and

''.example.com/''

These two patterns conflict with each other, causing the system to treat them as duplicate entities.

Solution: Simply remove one of the patterns to resolve the issue. It's recommended to keep the broader pattern .example.com/ as it already includes example.com.
