AttributeError: 'QSortFilterProxyModel' object has no attribute 'rootGroup'

[Benjamin Jakimow]

well known error since QGIS 3.18 (needs a QPS update)

AttributeError: 'QSortFilterProxyModel' object has no attribute 'rootGroup' 
Traceback (most recent call last):

spectral_libraries_plugin.py: - added some typehints - resolves#9 - takes care of $>qgis_process calls, where iface is None and not GUI required

Hi Benjamin,

I still encounter the error using QGIS 3.22 LTR.
Any ideas?

Many thanks,

Marcel
