Fix: use findOrFail instead of firstOrFail

[christmex]

If we use firstOrFail(), it will throw this error:

Illuminate\Database\QueryException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'some-ulid-or-id' in 'field list' (Connection: mysql, SQL: select `some-ulid-or-id` from `table_name` limit 1)
