2022-02-23 00:58:41.975 [error] Could not create schema migrations table. This error usually happens due to the following:

• The database does not exist
• The "schema_migrations" table, which Ecto uses for managing
  migrations, was defined by another library
• There is a deadlock while migrating (such as using concurrent
  indexes with a migration_lock)
  To fix the first issue, run "mix ecto.create".
  To address the second, you can run "mix ecto.drop" followed by
  "mix ecto.create". Alternatively you may configure Ecto to use
  another table and/or repository for managing migrations:

  What is ecto? How do I fix this?
  Thanks in advance
