Assumption
I am using docker to create an application. The first time I tried to deploy it to Heroku, it was deploying fine, but I got an error on heroku run rails db:migrate. I checked PG::UndefinedTable: ERROR: relation "users" does not exist and found that the error was caused by the fact that other tables related to users were run first due to migration. I have tried everything, but I can't seem to solve the problem, so I am asking this question.
What we want to achieve
I want to resolve the error and reflect the ``db

What we tried
- Changed the date of
2022040403234559_devise_token_auth_create_users.rbmigration file to20210403234559_devise_token_auth_create_users.rb. We then reset allDB, did a migration, and started over.But the error remained the same.

Rename the file from 20210403234559_devise_token_auth_create_users.rb to 00220403234559_devise_token_auth_create_users.rb after a re-push I used the heroku run rails db:migrate command and it worked.
