Below is the database configuration code:
connection: Env.get('DB_CONNECTION'),

| Configuration for MySQL database. Make sure to install the driver

Answer 1

Move to the root directory of your project and run your migration command:
node ace migration:run --force
If you encounter this error:
create table `adonis_schema_versions` (`version` int not null) - Unable to create or change a table without a primary key, when the system variable 'sql_require_primary_key' is set.
