[Exit Status 128] - Nbgitpuller Doesn't Allow Access to R.Datahub

Hello! We're using nbgitpuller in order to have students pull files from a remote repo. and there has been multiple students who have the following issue when trying to log onto r.datahub:


For nearly all students, it seems as if the file lab/lab01/lab01.Rmd manages to be staged but not fully committed, and thus during the pull it returns exit status 128. This also results in multiple duplicated files all throughout the students' datahub repos, in all the subdirectories.

I'm still not too sure as to how to duplicate this issue; it seems to be happening to different students at different times when they click the nbgitpuller link. This has yet to happen to me, but I'm really curious to see what exactly could be causing this thing.

Some insight on this issue would be super helpful! I can also provide additional details if needed. (Also please forgive me if I forgot something crucial; this is the first time I'm writing an issue report).
