Vaultwarden Data Loss Report: [error: cannot decrypt]

Steps to reproduce

  1. Login my vaultwarden account, and visit https://vault.torproject.org/#/vault?itemId=cc1f91c6-c9b9-46f7-832f-39c8e3ec4dfc&action=view
  2. Try to view the saved data.

What is the current bug behavior?

The following error show up in the console:

ERROR decrypt_with_key: bitwarden_crypto::enc_string::symmetric: error=The cipher's MAC doesn't match the expected value

[EncString Generic Decrypt] failed to decrypt encstring. Context: Property: name; ObjectContext: No Domain Context CryptoError: The cipher's MAC doesn't match the expected value

What is the expected correct behavior?

The original saved data should show up.

When did this start?
