You can see the log never bundle one. I changed the mempool from database to mempool and it worked. There must be a bug for database mempool. More specifically, the get_sorted_user_operations return from the uopool is empty when trying to bundle.

Sending userop without initcode is actually working. Wired bug. Could not find anything useful and reproduce it from tests
