error: failed to fetch some objects from 'https://127.0.0.1/PRJ/repo.git/info/lfs'Cause
The Git LFS version installed (3.0.x) on the Bamboo server seem to not be compatible with Bamboo and thus fails to checkout the code.
Solution
Downgrade the Git LFS installed on Bamboo Server to a lower version such as 2.13.x. This will be resolving the issue.
