Unexpected error has occurred when changing login w/ FF plugin

Help

When I try to update a login using the Firefox bitwarden extension, I get an error pop-up that indicates that an unexpected error has occurred.

I’m running vault warden in a docker container. When I encounter the error, I get this in the server’s logs:

[2026-02-05 19:44:58.314][request][INFO] GET /api/tasks
[2026-02-05 19:44:58.314][rocket::response::responder::][WARN] Response was None.
[2026-02-05 19:44:58.314][rocket::server::][WARN] Responding with registered (api_not_found) /api 404 catcher.
[2026-02-05 19:44:58.314][response][INFO] (web_files) GET /<p..> [10] => 404 Not Found
[2026-02-05 19:44:59.251][request][INFO] GET /alive
[2026-02-05 19:44:59.251][response][INFO] (alive) GET /alive => 200 OK

It seems like the change is committed to the database because when I reload…

Anyway, what can I do to get rid of this error message?

What version of Vaultwarden are you running? Given that the /api/tasks endpoint does appear to be missing I am suspecting that you are running an outdated version, so make sure you update to the latest release.

It looks like updating the server fixed it. I tried to update before posting, but docker hub wanted me to login… I was tired..

Thanks for the timely (and accurate) reply
