The issue is he pulled from git and the DB changes (local) were not working - but then what happened is no dB schema was created and just defaulted to the generic dB tables. So fails when trying to apply dB manager changes
When you clone an existing git project that have used the database manager to build up its scheme, then you just need to reapply those changes to your new local development target.
So just clone the project, build the local development in docker by choosing deploy.
Then go to the database manager - the database will be blank, but you will have all the changes, so just click on “Apply all the changes”. From the content menu and everything will be synched up
