git status returned

nodeJS exec does not work for cd shell cmd. as you see below, pwd works, git status is trying to work but fails because it is not executed in a git directory, but cd cmd fails stopping further successful execution of other cmds.
Tried in nodeJS shell as well as nodeJS+ExpressJS webserver.
