Problem

My repo is configured to use a GPG signing key, I'm trying to commit, but I got the following "gpg failed to sign the data" error:

My gitconfig contains:

user.signingkey=...
commit.gpgsign=true

which are also present in my Sourcegit settings: "User Signing Key" is filled and "Commit GPG signing" is checked.

Running git commit in the CLI does work, it prompts for my passphrase before creating the commit.

Sourcegit doesn't even prompt for my passphrase, and just fails 🤔
