1. Is this request related to a challenge you're experiencing? Tell me about your story.

I built a custom tool which allows upload file to the API. I tested in PostMan, it's working as expected. When I trying to call the API in Dify workflow, it fails the request with response "415". Screenshot as below: I seems Dify custom tools only accept json format request body, I'd like to see it accept uploaded files as well.

2. Additional context or comments

Postman request:

curl --request POST \
  --url http://localhost:5000/documents \
  --header 'Authorization: Bearer app-xxxx' \
  --header 'Content-Type: multipart/form-data' \
  --form '[email protected]' \
  --form type=upload
