Temp file problem in VARIANTS_IVAR:BCFTOOLS_SORT

[Paururo]

Description of the bug

Hello, I am running the test command to launch the pipeline on an HPC machine, but with version 2.6 I am having issues as it fails at the NFCORE_VIRALRECON:ILLUMINA:VARIANTS_IVAR:BCFTOOLS_SORT (SAMPLE1_PE) step. It reports an error that it cannot create a temporary file in my temp folder, which is empty and has write permissions. I saw this issue (#328) and did what was recommended, adding a config file to change the path of the temporary directory with the following content:
------------{custom.config}------------
process {
withName: '.:.:VARIANTS_IVAR:BCFTOOLS_SORT' {
ext.args = '--temp-dir ./'
}
}
------------{custom.config}------------
However, the error persists at the same step, stating that it cannot find the vcf file. If I run the same test command with version 2.4.1, it works without any problems. Any ideas on how to solve this would be appreciated, as it's unfortunate that the latest version isn't working.
