[Question]: Error on File Upload: Unknown filter parameter

[lzivan]

Describe your problem

I am experiencing an issue while trying to upload a test PDF file. The process fails and returns an error message stating an unknown filter parameter.

Could you please investigate this issue? I suspect it might be related to how parameters are parsed or processed during the upload.

Do you have error log?

No, there are simply normal logs for GET and POST
