Can't login with the BitWarden Firefox add-on?

Today I found I was unable to login to my Vaultwarden installation via the BitWarden Firefox addon, instead I got the cryptic error message “n is null”. Before today I was able to login with the Firefox addon. I can login to the web UI and I can login from an iOS client. I’ve tried updating the vaultwarden server and uninstalling/reinstalling the Firefox addon. Is this a known issue?

ah okay, after reviewing again it seems the docker image has moved, so when I updated it it didn’t actually come up to the latest version. I have moved to and it seems happy now.
