KeyError: 'suffix' when running fmriprepgr with all package requirements met

[snezanatodorovic]

Got the following error after "fmriprepgr '/bla/derivatives/fmriprep'", all package requirements are met, tested on several projects that used fmriprep.

fmriprepgr '/bla/derivatives/fmriprep'

Any suggestions? I am very new to this, sorry in advance if I am doing something wrong.
