When the Knowledge base widget’s request to retrieve widget settings fails because of an incorrect or outdated API key, the error returned does not indicate that the key is the cause, making it difficult to identify the root cause of a failing widget.

Update the widget settings API response so that a key-related failure returns a specific, descriptive error (for example, indicating an invalid or mismatched API key) rather than a generic error message that does not point to the actual cause.

Benefit: Users can identify and resolve API key issues on their own more quickly, reducing the time a widget spends in a non-working state.
