multipart/form-data is a form-data type that works with body payload or file upload.
Upload a File
Module which uploads a file to the service works with data type buffer in mappable parameters and type multipart/form-data in communication.
Notice the file input dialog, where the user can either choose the module that has a file available or manually map the file's name and data on their own.
This works only if the buffer is correctly implemented in in preceding modules.
