Git commit signing fails with `error: failed to fill whole buffer`

Which versions of Git and OpenSSH are you using? git --version && ssh -V


git version 2.40.1
OpenSSH_9.3p1, OpenSSL 3.0.9 30 May 2023


And the error message you're getting with op-ssh-sign, is that error: failed to fill whole buffer as well?

Correct. op-ssh-sign gives that whole buffer error.

I get this occasionally with the VSCode Git integration, though if I try again after it fails it usually works. I don't use the Git CLI very much but I don't think I've had the issue there, but could be wrong.

I am on macOS Ventura with 1Password for Mac 8.10.7 (81007041).
Git version: 2.41.0
OpenSSH version: OpenSSH_9.0p1, LibreSSL 3.3.6

I am receiving the same error in the same situation. Is there a remedy for this problem yet?

Installing the latest version of 1Password fixed it for me!

I'm now running 1Password 8.10.8, Git 2.41.0 and OpenSSH_9.3p1, OpenSSL 3.0.9 30 May 2023

Still happening for me intermittently on 1Password for Mac 8.10.9 (81009046).

Same issue here, using 1Password for Mac 8.10.9, only when using the VSCode integration. Using the git CLI works fine.

Also worth noting that this was working and stopped "all of the sudden". The "all of the sudden" may have been related to me installing the 1P Extension for Safari, though uninstalling it didn't solve the issue.

One more thing I noticed. Disabling some of the steps of my pre-commit got it to work with the VSCode Integration, so may be a race condition or timeout when committing that way.
