Map plots with latest iris=3.10.0 and cartopy=0.24.0 fail #3767
Description
Describe the bug
Running recipes that use iris to plot map plots (e.g., recipe_python.yml) currently fail with iris=3.10.0 and cartopy=0.24.0. This affects the current development version of ESMValTool, but also the released ESMValTool v2.11.0 on conda-forge (and possibly earlier versions, too).
Corresponding iris issue and PR:
- Remove
GeoAxespatch at next Cartopy release SciTools/iris#5977 - Update lock files, pin Cartopy!=0.23 SciTools/iris#6171
Here is the traceback:
