Describe the bug I tried to upgrade to new version pinax-eventlog for my app with djangoV3.0.8, Python 3.8,Mysql 5.7.22 and when trying to launch the instance i see this following error. When I looked at the migration file eventlog.0004_auto_20191205_2033 that is failing on it trying to grab a postgres field/variable (field=django.contrib.postgres.fields.jsonb.JSONField()) which my app doesn’t have
I see this issue with both 3.0.1 and 4.0.1 version and currently i was on v2 which did not had a problem. is there a work around for this?
