Review comment:
> Hello, is it possible to return directly here without continuing to
judge? In addition, it is not very intuitive to flood with too many if else
Hi, Thx a lot for your review.
Can you describe your opinion about why it need return directly? I think
this is an important step for users to debug zk or worker status errors.
