Using API Connector from API Workflows

I am trying to create a Google Calendar Event through the API Connector, and it works great in a regular workflow, but I can’t get it to work in API Workflows. On top of that, I am not able to see the error I get from Google.
I tried to add the api-endpoint to “Authorized redirect URIs” in the Google Developer Console, without luck.

Does anyone know how to use a API Connector in a API Workflow? Can it be done?

This is what it looks like in the API Workflows tab:

The error I am able to find, which doesn’t tell me much:

You can definitely use the API connector in an endpoint, just remember that in an endpoint you don’t have a logged in user – Since this is working in a workflow, that might be relevant. This can also trigger data privacy issues that might prevent the action from accessing data.

EDIT to clarify, you don’t have access to the logged in user if calling this endpoint from outside a bubble workflow!
