`PDOException: SQLSTATE[42000]: Syntax error or access violation: 1305 SAVEPOINT trans2 does not exist` in Laravel Testing

The error

PDOException: SQLSTATE[42000]: Syntax error or access violation: 1305 SAVEPOINT trans2 does not exist

The testing

I'm writing tests for my apis but I get this strange error in tests where I handle myself some errors using transactions with try-catch statements, e.g.:

public function controllerMethod()
{
    try{
        DB::beginTransaction();

        // do stuff

        DB::commit();

        return response()->json();
    }
    catch(\Exception $e){
        DB::rollback();
    
        return response()->json([], 500);
    }
}

I'm testing on a MySQL db and using the RefreshDatabase trait, and as far as I know in this case since I'm not using an in-memory db the trait perform an optimization executing the migrations only once and wrapping every test in a transaction that is rolled back at the end of each test.

When it occurs

As I said, the error arise only in the tests where I test the correct execution of the catch branch (usually in those test I remove an expected record from the db to cause an exception), while other tests works correctly: it's like that calling myself DB::rollback() mess up with Laravel's DB savepoints handling while testing due the RefreshDatabase trait.

Just to play with it I changed my rollback statement to DB::rollback(DB::transactionLevel() -2 ) and this seems to balance everything, making the test work correctly, but I cannot bring this modification to production.

How can I solve this problem?
