@Benjamin Jakimow your type annotations tends to lie
I would suggest to typeguard your functions and classes to assure type savety at runtime.

This would give you a much better error message:
File "D:\source\QGISPlugIns\enmap-box\enmapbox\externals\qps\utils.py", line 1921, in parseWavelength bandWLU = checkWavelengthUnit(wluKey, band.GetMetadataItem(wluKey, wlDomain)) TypeError: type of argument "value" must be str; got NoneType instead

Just use
@typecheckedas function decorator (from typeguard import typechecked)
