"An unexpected error has occurred" due to missing /api/tasks endpoint
-
The bitwarden desktop client app (2025.12.0) now requres an endpoint at /api/tasks when editing an entry. If that endpoint is not available, the client will report "An unexpected error has occurred", or something about an incorrect cipher.
The actual cause of the error is reported here: https://github.com/dani-garcia/vaultwarden/pull/6557
Until Vaultwarden is updated, users will continue to experience this with an upgraded desktop client.
