@dbanty I have tested this locally against a real server, not sure what other tests I could have added to this repo though?

[dbanty]

@csymeonides-mf thanks for both reporting this issue and providing a fix! I tweaked it a bit to reduce the extra generated code over in #355. Will you take a look at that and make sure it's still solving you problem?

[csymeonides-mf]

Yes thanks, that looks great! I wasn't sure if form and multipart are mutually exclusive, but I think it's a safe assumption.
