curl -X POST -F "file=@video.mp4;type=video/mp4" https://example.com
curl: (26) Failed to open/read local data from file/application

and

curl -F "data=test;type=test/test1" https://example.com
Warning: garbage at end of field specification: 1

however, removing the number in either of the types stops that error from occurring and uploads the file/data as expected.

I expected the following

This used to work, but from searching around a bit, I think this is what's causing the issue
