After git checkout, build returns: ERROR: Build failed: exit code 2

Anyone came across this issue using gitlab ci:



af5f746…f3500a4 master -> origin/master
Checking out f3500a46 as master…
ERROR: Build failed: exit code 2

I don’t understand, af5f746…f3500a4 -> this is commit id right ?

f3500a46 -> What is that or why wasn’t same as that -> af5f746
