Send option not working on Browser Extension

I have added the bitwarden Browser Extension and point it towards my self hosted vaultwarden instance (hosted via Docker)
The password manager side of things works fine.
However, I tried to add a file to the Send part to try it instead of my usual option TresoritSend.

But I keep getting an error message an unexpected Error has occured I cant see any way to debug this error
I logged into vaultwarden and was able to upload the file fine but it would be more convenient to be able to use the browser extension

Can anyone help with this?
