Dmriprep error: "NoneType object has no atribute 'get'"

We are hoping to utilize dmriprep to process our diffusion data. As a first pass, we have a small, bids-verified dataset we were hoping to test with it.

We set up the command as follows:

cd $processing_dir

for i in sub-*; do
	docker run -ti --rm \
		-v ${PWD}:/inputs \
		-v ${PWD}/derivatives/:/outputs \
		-v ${license_dir}/license:/license \
		-t --user $(id -u):$(id -g) \
		nipreps/dmriprep:latest \
		/inputs /outputs \
		participant --participant-label ${i} \
		--fs-license-file /license/license.txt \
		--fs-no-reconall
done

When running, we encounter the following error:

Process Process-2:

AttributeError: 'NoneType' object has no attribute 'get'

The same issue has been reported sometime ago on the github project page, which was due to a “path issue”. I cannot figure out which path is incorrect in our command
