What happened?

Sending image in any chat gives 422 error in console.
Cannot add any profile picture or attachment.

What I already did

Tried to forward api and Autumn through separate subdomains AND sub-locations.
Tried to use newest tagged API image.
Tried to change paths to Revolt pieces in Revolt.toml.
Tried to change "production" option in Revolt.toml.

Thanks for your work! I'll try my best to help you reproduce and fix this issue. Whether it's a real bug or just an error on my side. ^^

Seems like Revolt catches nothing. In logs there is "null" value instead of string. Found it while working, kinda nooby myself, thanks for my collegue.)
