Http 500 Error on POST pictures

That's an error in your homeserver

[muellerjoel]

Are you shure? In private whatsapp rooms the pictures are shown normal

[tulir]

Yes, that's what "internal server error" means: the server that handled the request is broken. /_matrix/media/v3/upload is usually handled by the homeserver, or if you have a separate media repo then by that server.

Ok. Wired. Why should video work in the same broadcast room and pictures not and so pictures in normal bridge rooms too.

Ok i found out the error it’s about sqlite version. Sqlite 3.40 is all ok with 3.42 the internal error shows up

hi @muellerjoel

have the same error message with the generated QR Code. Can you tell me how you downgrade the Sqlite Version?

ERR Failed to upload QR code: failed to POST /_matrix/media/v3/upload: M_UNKNOWN (HTTP 500):

Hi
Which Distro do you have?

For Arch Linux go to https://archive.archlinux.org browse s and go to the right sqlite version copy the url

do curl -o URL and then pacman -U sqlite-XXXXX

Restart synapse and the bridge with systemd service

Cheers

I had the same error with a matrix synapse installed via pip.
Posting images to unencrypted rooms (like whatsapp) was not possible.
For me, this was solved by

pip install -U pillow==9.5.0

Thanks. That Works @uvolmer @muellerjoel

Downgrading Pillow worked for me (but not downgrading SQLite).

Does anyone know why this bug started occurring in the first place? I can't see any details from the logs, and, even though downgrading Pillow is a workaround that works for now, I can't keep it on a lower version without breaking other Python system packages.

The synapse bugreport of the pillow bug is below.
As far as I know, it is fixed in synapse version 1.88.0
