When trying to run WPS-Download community module example mentioned at this link
https://docs.geoserver.org/stable/en/user/community/wps-download/rawDownload.html#sample-request
got following error:

Based on debug, error is generated in line 220 at this file since coverageDimensionInfoList.get .getDimensionType() value is null, so then getSize() call fails.
Based on testing using default geoserver data_dir, it’s required to update the bands definitions on the raster files referenced by gs:Download, in order to make it work. For some reason, those values are not correct when trying to use the mentioned module (which attempts to calculate size based on that values)
