Content-type boundary None when upload to API

[TheCrott]

I encountered an error when upload to my API. I test with postman and httpie it's working, but when use base64 plugin I got error "Invalid boundary in multipart: None". I already set "Content-Type: multipart/form-data" in ionic post header to my API but still got error.

http --verbose --form POST myapi.com/resources/ [email protected] name=Clark

Here is the output from httpie
