 I'm encountering some issues when trying to follow the world app geodjango
 tutorial step by step as documented:
 [https://docs.djangoproject.com/en/4.2/ref/contrib/gis/tutorial/]

 I had trouble with this error when trying to complete the layermapping
 step:
 [https://docs.djangoproject.com/en/4.2/ref/contrib/gis/tutorial/#layermapping]

 So I skipped that and encountered it again when trying the spatial
 lookups: [https://docs.djangoproject.com/en/4.2/ref/contrib/gis/tutorial
 /#spatial-lookups]

 ogrinspect worked so I assume I have geos and gdal libraries configured
 correctly. My database is confirmed to have POSTGIS 3.0.

 lookups]
