Hi @sonu90das
your user doesn’t have permissions to modify bts_xxxxxxxxx/xxxxxxxxx/xxxxxxxxx/.git/config
you can use ls -l bts_xxxxxxxxx/xxxxxxxxx/xxxxxxxxx/.git/config to see what permissions are set and who is set as owner and group.
Then ask owner of the file or someone with root privileges to update it’s permissions so you get access.
As an alternative you could create your own workspace and clone the repo.
