+### Workaround
 
   Per [the installation steps](https://github.com/blacs30/bitwarden-alfred-workflow#installation), you **_MUST_** add Alfred to the list of Developer Tool exceptions for Alfred to run any workflow that contains an executable (like this one)

+## Unexpected error. Exit code -1.
 
+  Using `bw` cli and this workflow in parallel can possibly cause this error occurs `Unexpected error. Exit code -1.`
   The reason for that is when the `bw` cli is used in the terminal and the password is entered that a new session is initiated and the workflow's session invalidated.

+### Workaround
 
   You can use the bash functions created by @luckman212 and located [here in github](https://github.com/luckman212/bitwarden-cli-helpers)<br>
   Download the bash file and source it in your own `.bash_profile` or `.zshrc`

+**NB: The workflow's internal decryption mechanism is currently not working. Follow [issue 171](https://github.com/blacs30/bitwarden-alfred-workflow/issues/171) for progress on this issue.**
 
   With version 2.2.0 this workflow decrypts the secrets without using the `bw` cli. This is much faster but it might possibly can fail.<br>
   If it fails it falls back and uses the `bw` cli to get the secret. The decryption takes then more time again, was in the previous versions.<br>

   The linked doc doesn't specify how to force creation of a new key. It's easy though:
