q2-itsxpress bbmerge error

I am back in using q2-itsxpress with qiime2.2020.11 and I got the flowing error
~$ qiime itsxpress trim-pair-output-unmerged --i-per-sample-sequences demux_sp001.qza --p-region ITS1 --p-taxa F --p-cluster-id 1.0 --o-trimmed demux_sp001_trimmed.qza

Plugin error from itsxpress:

Command ‘[‘bbmerge.sh’, ‘in=/tmp/qiime2-archive-lk8lgl1p/b57c11b9-3dfc-49c7-b759-288d1f83f153/data/Neg1_64_L001_R1_001.fastq.gz’, ‘in2=/tmp/qiime2-archive-lk8lgl1p/b57c11b9-3dfc-49c7-b759-288d1f83f153/data/Neg1_64_L001_R2_001.fastq.gz’, ‘out=/tmp/itsxpress__y8_4e0w/seq.fq.gz’, ‘t=1’, ‘maxmismatches=40’, ‘maxratio=0.3’]’ returned non-zero exit status 1.

Debug info has been saved to /tmp/qiime2-q2cli-err-824o6ss6.log

I would appreciated any inputs to solve this issue!

You need to update bbtools from within your qiime2 conda environment. It uses a feature only found in more recent versions.
