SEBE - TypeError: can only concatenate str (not "NoneType") to str

[fondoflife]

hi there,
i am stuck trying to use SEBE.
it returns the following error:

Traceback (most recent call last):
File "C:/Users/Tomas/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\UMEP\SEBE\sebe.py", line 473, in start_progress
self.folderPathMetdata[0], albedo, onlyglobal, trunkratio, psi, sizex, sizey)
File "C:/Users/Tomas/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\UMEP\SEBE\WriteMetaDataSEBE.py", line 27, in writeRunInfo
file.write('Projected referece system: ' + srs.GetAttrValue('projcs'))
TypeError: can only concatenate str (not "NoneType") to str

project and layer CRS are equally set.
what causes this error?

any help or suggestions greatly appreciated.

CRS is retrieved from your DSM layer and for some reason it is of NoneType in your case. If you right-click on your DSM and investigate the CRS given in the Information tab. What does it say?
