TypeError: batch_run_sample() takes from 16 to 17 positional arguments but 18 were given

I am trying to run the CNVkit 0.9.11.dev0 copy number calling pipeline for a whole exome sequencing sample. However, I am encountering a type error TypeError:batch_run_sample() takes from 16 to 17 positional arguments but 18 were given. I am using the following options with the batch command:

cnvkit.py batch tumour.bam -n -t xgen_plus_spikein.GRCh38.bed -f hg38_masked.fa --annotate hg38.refGene.filtered.bed -p 1

The pipeline runs until the following step and then fails:
