Solutions

1. Fix the request built inside the custom-api template via 'newRequest'/'withURL'/etc.: provide a valid URL and valid headers/parameters.
2. Check the underlying initialization error included in the message (e.g. URL parsing) and correct the corresponding template call.

When it happens

Trigger: Occurs when building an HTTP request for the custom-api widget fails, e.g. an invalid URL, invalid header value, or unsupported method.

Common situations: A malformed URL in the widget config, headers containing illegal characters, or a template producing an invalid URL at runtime.
