Data 360 : Einstein Studio Authentication Fails When Connecting to Databricks Endpoint

When attempting to connect a Databricks model endpoint to Einstein Studio, users may encounter an authentication error. This can happen even if the endpoint appears functional and returns responses via tools like Postman.

Cause

Einstein Studio uses OpenConnector to interface with external model endpoints. OpenConnector expects the endpoint URL to follow a specific format. If the provided URL does not end with /chat/completions, OpenConnector may fail to connect by appending this path automatically—resulting in an error.

Error Message Example

Unhandled provider error: 
{
  "error_code": "ENDPOINT_NOT_FOUND",
  "message": "Path must be of form /serving-endpoints/<endpoint_name>/invocations or /served-models/<served_model_name>/invocations"
}
