Authentication problem with Adapters.ODataV4Adaptor

Question

Hi. I have a problem with the Authorization Bearer header, I checked the forums and found two ways to do:

HeaderData.Add("Authorization", "Bearer” + “token");
HeaderData.Add("Bearer", "token");

I've tried both and the result is the same, an unauthorized 401 response.

Check my request on postman and it works fine.

Here is my Control configuration:

* I have not sent both at the same time.

Network:

The weird thing is that I can authenticate the user once the function starts.

It could be a problem with my api, but then why does it work well in postman?

Thank you very much for your attention, I await your response.
