HTTP Basic Auth - bubble vs postman

I have setup a api call with http basic auth in both bubble and postman, and it works fine in postman, but just fails and gives this message in bubble: {“message”:“Invalid email or password”,“errors”:null}

The username should be empty, and i’m wondering if Bubble can’t handle a empty username?
Or is there anything different about the Http basic auth in bubble and postman?

Also tested with Zapier webhook and also works fine with that.
