Answer 1

You have accidently changed the methods in vendor folder.
Step 1.
delete the vendor folder.
Step 2.
run
composer install
It will install all the libraries again and overwrite changes.
Hope this helps

Answer 2

It's quite difficult to say without looking at full error log, but there is alternate for this, if you create down methods for your migration by providing specific database connection like this
Schema::connection('mysql2')->create('some_table', function($table)
{
$table->increments('id'):
});
Then only php artisan migrate:rollback will work perfectly for this.

Answer 3

If you look in your migrations table, then you’ll see each migration
has a batch number. So when you roll back, it rolls back each
migration that was part of the last batch.
If you only want to roll back the very last migration, then just
increment the batch number by one. Then next time you run the rollback
command, it’ll only roll back that one migration as it’s in a “batch” of
its own.

Hi thanks your all to take your time to answered my question. I found what going on. In one ove my migration, in the down function I have a function was misspelled
public function down()
{
if (Schema::dddconnection('system')->hasTable('apiservices_categories_translations')) {
Schema::connection('system')->dropIfExists('apiservices_categories_translations');
}
}
