-- Requested enhancement description (What would you like to accomplish?) --

When trying to connect to the billing API using Dialogflow playbook, the workflow is returning an empty error message.

This is related to a billing implementation which requires calling the billing API using Dialogflow playbooks. When calling the API, it just returns an error without any specification. It is understandable that errors can be encountered, but it is expected those errors to be more specific (e. g. 40x, 50x etc.).

In other words, the agent execution fails at the API call step, but the error output lacks any detail that would help in debugging the issue (e.g. HTTP status codes, response body from the API, etc.).

Please see the attachments as well.

-- Detailed functionality description (How might it work? What needs to be changed?) --

A constructive error message should be returned without the need to review the logs or to raise a support case for debugging.


-- If applicable, reasons why alternative solutions are not sufficient --

Not having a clear message is affecting developments because there is the need to raise support cases in order to seek help which is time consuming. There is no alternative solution I could identify for this (other than logs).

-- Other information (workarounds you have tried, documentation consulted, etc) --
