What happened?

I am trying to analyse multiplexed Cas9 enriched sequencing data with the Epi2ME Cas9 workflow. However, the code runs until 'pipeline:pack_files_into_sample_dirs (16)' and then produces the following error:
ERROR ~ Error executing process > 'pipeline:pack_files_into_sample_dirs (16)'
Caused by:
Not a valid path value type: java.util.ArrayList ([/mnt/c/Users/prov/epi2melabs/instances/wf-cas9_01J28TTX6Z6X38C11D3HBJMSEG/work/56/9aa8eda5d322cbe26a001358c5c804/barcode17_target_cov.tsv, /mnt/c/Users/prov/epi2melabs/instances/wf-cas9_01J28TTX6Z6X38C11D3HBJMSEG/work/56/9aa8eda5d322cbe26a001358c5c804/{meta.alias}_target_cov.tsv])

Hi @Vtsseq. Could you paste the text from the log tab please?

[nrhorner]

HI @Vtsseq

This seems to be a bug that you have found. I think it should only occur when there are no reads mapping to the reverse strand.I'll get a fix out for this ASAP

Hi nrhorner, thank you for your answer, here is the log of the instance if you still need it.

Thanks for the log. I'll let you know when that fix is release.
