Endpoint with ID '{endpoint_id}' not found

Error message

Endpoint with ID '{endpoint_id}' not found

What it means

Thrown during pass-through endpoint update: after loading the configured pass_through_endpoints list from the config store, no entry with the given endpoint_id exists (it may have been deleted or the ID is wrong), so there is nothing to modify.

Solutions

1. Verify the endpoint_id with the list endpoint (GET pass-through endpoints); use the exact ID returned.
2. The endpoint may have been deleted; recreate it if needed.
