Errors After Upate v6.27.12

I think solution is here Error while making bench migrate

For me it worked

  1. bench switch-to-master
  2. bench update --patch - it will show some error
  3. bench mysql
  4. ALTER TABLE tabDocType DROP COLUMN track_seen;
  5. ALTER TABLE tabDocType DROP COLUMN quick_entry;
  6. Exit the SQL terminal, and run bench update
