At least one field must be provided for update

Error message

At least one field must be provided for update

What it means

Input guard on PATCH-style update of Vantage settings: the request body contained no api_key, integration_token, or base_url, so the partial-update endpoint has nothing to apply and rejects with 400 rather than performing a no-op write.
