yamyamyuo commented on issue #4636: can not merge to mysql URL: https://github.com/apache/incubator-superset/issues/4636#issuecomment-373996035 I also ran into this error today. I assume that this issue may have something to do with the switch of version of superset. I firstly use 0.23.0dev, then switch to 0.22.1. When I cleanup everything in my db and install 0.22.1 again, this error disappear. Also, the upgrade of superset version can run into many issues. I upgrade superset from 0.22.1 to 0.23.2, it always warning FAB view is None. I checked my db and found there were some null data in `ab_permission_view` table. I just wonder if I want to upgrade my production superset, what should I do. I just can't mess up the database with different versions.
