Signing git commits issue

I wanted to try the new "sign git commits" feature and did everything exactly as described in the docs

But when i try to commit something now im getting the following error


error: unsupported value for gpg.format: ssh
fatal: bad config variable 'gpg.format' in file 'C:/Users/fabia/.gitconfig' at line 15

upon looking at the .gitconfig file everything looks fine

[gpg]
format = ssh
[gpg "ssh"]
program = C:\\Users\\fabia\\AppData\\Local\\1Password\\app\\8\\op-ssh-sign.exe
[commit]
gpgsign = true

does this have something to do with the op-ssh-sign.exe?

    Signing commits with SSH keys was introduced in Git 2.34, could you check your Git version: git --version?

    i had an older version and just updated git to 2.37.3

    the error above disappeared but a new one appeared
    ```
    error: Error: AppError { error: could not authenticate with ssh agent, location: Location { file: "ssh\op-ssh-sign\src\ops.rs", line: 95, col: 37 } }

    fatal: failed to write commit object
    ```

    Hi @Fabian9799, glad to hear that you're one step closer! As for the new error you're seeing, please make sure that the key is located within your Private vault.

    Just checked. It's already in my private vault

    Hi @Fabian9799 thanks for confirming that. Can you double check if you can simply authenticate with SSH? For example, if you're set up with GitHub:


    ssh -T git@github.com

    Assuming that works correctly, do you see anything appear in the 1Password logs when you perform the Git command? On Windows: %LOCALAPPDATA%/1Password/logs.

    When running ssh -T git@github.com the only message i get is

    git@github.com: Permission denied (publickey).

    but when running ssh -vT git@github.com a connection can be made

    FWIW, I am experiencing the same thing, even though I can log into a local gitlab instance.

    ```
    ❯ ssh -T git@gitlab.jinkit.com
    Warning: Permanently added 'gitlab.jinkit.com' (ED25519) to the list of known hosts.
    Welcome to GitLab, @v1k0d3n!

    ❯ git commit -s -m "update README"
    error: Error: AppError { error: could not authenticate with ssh agent, location: Location { file: "ssh/op-ssh-sign/src/ops.rs", line: 95, col: 37 } }

    fatal: failed to write commit object
