File upload failed.

Error message

File upload failed.

What it means

Generic failure response of the POST /system/upload-pfp endpoint: the profile-picture upload pipeline (multer handling via handlePfpUpload middleware or the subsequent save) threw, and no uploaded file name was produced or an exception escaped the try block. It is a catch-all 400/500 sentinel for avatar upload failures.
