Error in update to latest 8.0.29

Same error again. It is strange that doctype Student Group Instructor does not exist in db.

Can you check if json file is in the Student Group Instructor doctype folder?

Before update student group instructor wasn’t exist in doctype and db. After update started doctype was created but does not exist in db.

Json file exist

I try with this comand bench reload-doc schools doctype student_group_instructor and now update is completed. After that i restart vm and now there is new problem with mysql server. OperationalError: (2002, ‘Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2 “No such file or directory”)’)

Thanks guys for help. I finally solve the problem on latest update (8.1). I also have error with students group. I solve the problem deleting students group data from database. Thanks again.
