Missing Authorization Header error ins Flutterflow when Multipart API Call with Buildship and Firebase

Hi,

I am trying to call Buildship's "Upload File to Firebase Storage (Authenticated)" API from Flutterflow, in order to upload an image to Firebase.

Below are the screenshots from:

1. Flutterflow Action with the 2 variables Image and token.

2. the API Header

3. the API variables

4. and the Code from the Buildship node, that throws the error.

5. selecting the JWT token

I spent 2 days now to figure out, how to add the token to the authorization header within a Multipart API Call - without any success. Any idea is grealty appreciated 🙂
