bedGraphToBigWig sort error

[ChrDec]

Hi,

I am getting the following error:

2020-04-28T10:42:37+02:00,ERROR: Job bedGraphToBigWig-coverage.bedgraph.1 failed with exit code 255. Job logs:

Job error message:

One or more errors occurred. (Job bedGraphToBigWig-coverage.bedgraph.1 failed with exit code 255)

I am using dotnet v2.2.207, the latest version of canvas in SmallPedigree-WGS mode and I updated bedGraphToBigWig to v2.8.

Thank you very much for your help.

Kind regards
Chris
