Laravel transactions don't rollback on exception in MySQL with InnoDB engine

I have this transaction, and all my MySQL tables are using InnoDB engine :

\DB::beginTransaction();
try{
    User::create([
        'name' => 'test',
        'status' => 1
    ]);
    array_push($test_array, ['test']);
    \DB::commit();

} catch(\Exception $e){
    \DB::rollBack();
}

If I dump() the exception, it says array_push() expects parameter 1 to be array, null given, because $test_array is null, but the transaction didn't rollback, and the user is still created. I don't know what I'm doing wrong.

I get the same result while doing this too :

\DB::transaction(function () {

    User::create([
        'name' => 'test',
        'status' => 1
    ]);
    array_push($test_array, ['test']);
});
