Question about DSM Generator

[htsltiago2021]

I have an error when I try to create the DSM for my area.
What may be occurring?

Thank you

The error is as follows:
2021-03-21T18:40:40 WARNING Traceback (most recent call last):
File "C:/Users/.../AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\UMEP\DSMGenerator\dsm_generator.py", line 645, in start_progress

This error is not related to SVFCaclulator but to the DSMGenerator.

How do you define your area in the DSMGenerator?

[htsltiago2021]

through 'the extent from layer'

[biglimp]

Could you then please attach the layer that you are using.
