API Connector Initialisation

Hi

is it possible to make the CURL or the JSON visible with which the API Connector initializes the API Call.

I have the problem that I have an API Call to our backend with multiple Files.

I made an API request that looks like this →

but when I try to initialize it I get an error because the Filesize of those empty file uploads is not 0 or is greater than 0.

When I use Postman like this →

it works but when I try to init the API Request in a similar way with bubble it seems that the empty files are not empty or the filesize is greater than 0 what leads to an error in my backend…

Any Ideas?

Thank you very much for all your hard work!

kind regards
Thomas
