Version

2024.03

What were you trying to do?

shitpost

specifically, by uploading a picture attachment

What did you expect to happen?

shitpost

specifically, by publishing a post with the requested picture attachment

What actually happened?

The attachment did not get successfully uploaded. Further attempts at uploading any attachments failed.

Attempting to load my akkoma-fe homepage now results in a blank screen. Only the following error is reported by the server on load:

Oddly enough, that file exists and can be retrieved via SSH. It's not the attachment media, but the akkoma-fe header icon.

In addition, trying to use a different client to upload new media returns an Internal Server Error, with the server reporting messages like this:

I'm using local media storage, no S3 buckets or anything alike.

Severity

Worth noting: deleting the drafts key from local akkoma-fe storage did bring the UI back. Creating a new draft with a new upload breaks the UI once again. I found this is due to the presence of an object key "files":[{}].

The header icon looks gone despite being stored locally ofc, so I went to admin settings to delete and reupload the instance logo, but reuploading failed with the same no function clause matching in IO.chardata_to_string/1 error as above.
