express gateway doesn't pass multipart/formdata

Question

I'm using express gateway as my gateway to services. one of my services has to update an image. so when I'm using the service alone it accepts files and I use multer to parse them but when it's behind express gateway, the file will be lost and I don't have that in my body afterward. Is there a config for such a thing?

I've used this config but it didn't work:

    policies:
  - request-transformer:
      - action:
            multipart: true
  - cors:
      - action:
          credentials: true

so after lots of searching, I finally found the problem. the request-transformer policy was the problem and by removing that, it worked just fine and I don't why it caused the problem. so my final pipeline config is like this:

  project:
    apiEndpoints:
      - project
    policies:
      - cors:
          - action:
              credentials: true
      - proxy:
          - action:
              serviceEndpoint: project
              changeOrigin: false
