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

FWIW: I came across this Problem using the WebStorm git integration on Ubuntu. The solution for me: if the git operation doesn't go through immediately, check the 1Password tray icon for a red "notification" dot; if present: click it, there should be a "SSH request waiting..." menu entry. Click that and the 1Password dialog should pop up and after that the git operation went through for me.

In other words: For me it was a timeout problem caused by the fact that the 1Password SSH-key-unlock-dialog didn't pop up.

We were finally able to reproduce the issue and fix it. The fix will be out in next week's beta release. If you already want it today, you can also find the fix on the nightly release channel.

Let me know if it solved it for you!

@floris_1P what's the version that will get released in? I get it consistently in VSCode, but not in my shell.

@floris_1P I can confirm that this issue is fixed for me in the latest beta release.

@floris_1P works for me now out of WebStorm, using the latest production release, thank you so much!

I'm still getting this same error when using vscode on mac using the remote plugin to access windows with 8.10.24
