HTTP 400 error, when publishing assets to Curseforge

[MagnusHJensen]

When using mc-publish and hitting the upload to CF step, I get the following error, but no description as to why.

I've also tried to run it with debug logging, but no useful error appears.

I was a dork, combining 3.3 syntax with 3.2 version.
