Running git-commands in a shell within the service

[NWRUS]

Hello!

I have trouble figuring out the route cause of my problem. Any help is appreciated.

I'm running on node v22.14.0 and npm v10.9.2 and latest version of node-windows

My script has multiple call of a spawnSync():

///< exec shell cmd
var shellCmd = (cmd, path) => {
    log("[SHELL CWD]: " + path);
    log("[SHELL]: >> " + cmd);
    
    const result = spawnSync(
        cmd,
        {
            stdio: ['ignore', 'pipe', 'pipe'],
            encoding: 'utf-8',
            shell: true,
            cwd: path
        }
    );

    if(result.stdout.length)
    {
        log("[SHELL]: >> (stdout) " + result.stdout);
        return result.stdout;
    }
    
    if(result.stderr.length)
    {
        log("[SHELL]: >> (stderr) " + result.stderr);
        return result.stderr;
    }

    return "";
};

I mostly use it to run git commands. All works smoothly in the script, but breaks in the service. Certain git commands (the ones talking to remote) hanging the shell and entire script. It doesn't show any error, and stdout/stderr are empty. For example here:

            ///< check if our repo is added as remote, if not - add it
            var result = shellCmd("git remote -v", prjObj.path);
            if(result.includes(config.gitRemoteName))
            {
                log(`[GIT]: Already contains ${config.gitRemoteName} as second remote`);
            }
            else
            {
                log(`[GIT]: Adding ${config.gitRemoteName} as second remote`);
                shellCmd(`git remote add ${config.gitRemoteName} ${prjObj.repo}`, prjObj.path);
            }
            ///< get fresh head and make one push just in case
            prjObj.head = shellCmd("git rev-parse HEAD", prjObj.path).toString();
            shellCmd(`git push ${config.gitRemoteName} --force`, prjObj.path);

Only git push --force fails, everything else executes normally. I have number of pulls, updates etc across the script, they all fail similarly.

What could be the problem? Credential manager? System user limitations etc.?

Thanks
