Bash errors when running nextflow with latest version (19.07.0)

[cimendes]

All FlowCraft pipelines have been failing in the latest version of nextflow (installed through conda). The errors are fairly general.

For example I created a simple pipeline with just one component with flowcraft build -t "fastqc" -o fastqc and ran it with nextflow run fastqc.nf -profile docker on a single sample. This was my output:

When looking at the .command.log files of each fastqc process, we obtain the following:

The bash errors thrown are not very informative and I still haven't been able to figure out what is the underlying cause. This pipeline works well with previous versions of nextflow (tested with 18.10.1).

Input on this issue is very welcomed!

If i disable the trace file in the nextflow.config, it works (until it dies because trace files are a necessary thing!). Removing either of trace file fields makes no difference. This problem occurs with either container software.
