Hi list,
I've been having issues with newer versions of Geoserver and its WMS
GetFeatureInfo requests (styles with ras:RasterAsPointCollection
transformation on ImageMosaic layers). As I was trying to get to the
bottom of it, I noticed the logs seem incorrect compared to the source
code (git repo). I've tried 2.22.2 and 2.23.0, where both GetFeatureInfo
requests of layers with said styles end up with a 'The image
"https://..."; cannot be displayed because it contains errors'. 2.20.4
works fine. On either of the versions that produce the error, the logs have:
org.geoserver.platform.ServiceException: Failed to run GetFeatureInfo on
layer models:model_highcloud
*at org.geoserver.wms.GetFeatureInfo.execute(GetFeatureInfo.java:90)*
at org.geoserver.wms.GetFeatureInfo.run(GetFeatureInfo.java:42)

But the highlighted line at *GetFeatureInfo.java:90 *doesn't actually
have the ServiceException there (according to the 2.22.x and 2.23.x
branches of the geoserver repository). On 2.21.x and downwards I do see
the ServiceException being thrown at line 90.
Could somebody please enlighten me on what is going on in the logs or
what am I missing?
I will include the files required to create a minimalistic example for
the ImageMosaic layer & style.
Cheers,
Kamilla
