Upload multiple files with form-data

[psutak]

Hello, I'm trying to upload multiple files with aditional form-data. When I send the data using Postman to 3rd party rest api, everything is fine.

When I inspect Postman request, I see this:

But when sending the same data from node-red (http-request node), the form data is serialized as a string and not as an array

Is it possible to somehow achieve the same behaviour as the postman does

Thanks.
