ParseFile.save() Fails with "POST must have a request body" v1.13.1

[StuStirling]

When updating to v1.13.1 I could no longer save files. Downgrading enabled file upload again. Here is the exception:

ParseFile creation and upload definitely correct because I have been using it for a while and downgrading immediately resolved the issue
