Description
When I try to run the 'random points inside polygon' algorithm in QGIS 2.99 I get the following error :
Processing algorithm...
Algorithm 'Random points inside polygons' starting...
Input parameters:
{ 'INPUT' : '/Users/admin/Downloads/TutoQGIS_Donnees/TutoQGIS_10_Representation/donnees/COMMUNE.shp', 'STRATEGY' : 0, 'EXPRESSION' : 'POPULATION * 10', 'MIN_DISTANCE' : 0, 'OUTPUT' : 'memory:' }
Traceback (most recent call last): File "/usr/local/Cellar/qgis3-dev/2.99/QGIS.app/Contents/MacOS/../Resources/python/plugins/processing/algs/qgis/RandomPointsPolygons.py", line 120, in processAlgorithm raise ProcessingException( NameError: name 'ProcessingException' is not defined
Execution failed after 0.08 seconds
The shapefile used (COMMUNE.shp) can be found here : http://ouvrir.passages.cnrs.fr/tutoqgis/donnees/TutoQGIS_10_Representation.zip
The same operation in QGIS 2.18 works and produces the desired result.

Fixes #18103
[processing] Don't throw an exception if an expression cannot
be prepared
There's cases where this happens without reflecting an invalid
expression. So we can try to prepare, but not abort if the
preparation fails.

Thanks for the rapid fix and the speed improvement! It's really nice.
I'm afraid there seems to still be an issue when using the "Selected features only" option.
