Hello,

First, thanks a lot for AMC!

I'm using AMC through the CLI. I made some attempts to make sure that I was dealing correctly with the various commands, and my attempts were successful as I succeeded to obtain annotated PDFs of test student sheets and a CSV with their marks.

Now, I've used AMC in a real situation and the annotation doesn't work. The automatic association has (partly) been successful. I managed manually the special cases and it was ok. I was also able to export the marks with `auto-multiple-choice export`, which shows that the correction and the associations were successful. However when using `auto-multiple-choice annotate` to annotate the students sheets, I have several warning messages such as:

Use of uninitialized value $code in hash element at /usr/share/perl5/AMC/Path.pm line 78, <GEN29> line 14.
Use of uninitialized value $rep in pattern match (m//) at /usr/share/perl5/AMC/Path.pm line 81, <GEN29> line 14.
Use of uninitialized value $code in hash element at /usr/share/perl5/AMC/Path.pm line 78, <GEN29> line 14.
Use of uninitialized value $rep in pattern match (m//) at /usr/share/perl5/AMC/Path.pm line 81, <GEN29> line 14.

(with the line number at the end of the line being 14+4*n)

And the produced PDF are empty (the file is not empty, but the content of the PDF is).

Here is the command line I used (but as mentioned previously, it was successful when I made some tests):

auto-multiple-choice annotate --project 1_comptage/ --data "1_comptage/data/" --names-file "../../22-23/ASDG4_qcm.csv" --pdf-dir "/tmp/test" 

Do you have any insight on what could be wrong here and how I could fix that?

Thanks a lot,
Mikaël
