Upload multipart form data in parse server class

Hello folks!

  1. js application + axios + post request w/ multipart form data (3 binaries: audio/photo/video) and some string key:values
  2. parse server w/ predefined schema for my classes/MyClass

can i upload all files via post on classes/MyClass ? or i need to use parse/files API that map uploaded files w/ class object? currently i am getting
