Kindly check and let me know the solution to proceed further .

Reproduce the migration from 8.13.6 to 8.14.0 or the reported 8.14.1 image and start with db/migrate/20161017091941_add_authorized_projects_populated_to_users.rb. Inspect config/initializers/connection_fix.rb and the MySQL logs around the ALTER TABLE failure; done means the migration completes without losing the connection.
