The issue says that there is an NPE. But I don't see a relationship between the issue and this pr.

Could you please explain it?

There are two problems with this issues, one is null and the other is a language code problem that I can split into two issues

[weihubeats]

@drpmma Can this pr be merged?

[weihubeats]

Is this pr ready for merge, and are there any other issues that need to be dealt with?

[RongtongJin]

@weihubeats How about merging lastest code to trigger CI again？

[weihubeats]

@RongtongJin I merge the latest dev bis triggered ci, but a few cid still failed, I feel that this should not be the result of this modification, this test these failed use cases can be successful!
