Random lpass Error: Could not find decryption key

[psciacca2inno]

I have a batch shell script that runs inside a Jenkins server. It uses lpass cli to retrieve secure notes from lastpass.
This task is launched several times (about 200 times or more) both in the day and night.

I'm quite sure that this proceess have no error in the day, but sometimes in night hours,
randomly gives error:
"lpass Error: Could not find decryption key Perhaps you need to login with lpass login."

Is there any way to debug the lastpass-cli commands ? or additional info and try to solve this error ?

For example yesterday I missed 8 backups for this error.

Thanks in advance.

I've been encountering the same issue in our scripts. Reading the source, I think what happens is that lastpass-cli spawns an agent and then immediately exits on login. If you try to immediately run lpass show, the agent won't be up / connected to the socket yet, and that will cause the command to fail. This isn't entirely deterministic, since sometimes by the time lpass show executes, the agent will be far along enough in the bringup process where it is binded to the socket.

Throwing a sleep for a little bit after the login will probably fix it. The --plaintext-key option should also work since it would bypass the agent entirely, but that doesn't work in our case since we don't want to write they key to disk. I'm looking into writing a patch so that the lpass login command will wait for the agent to bind to the socket before exiting. I'll try to submit a PR if I figure it out.
