Author: nbghereCreated Apr 15, 2026Updated Aug 27, 2026
Integrity requirements
- I have read all the comments in the issue template and ensured that this issue meet the requirements.
- I confirm that I have read the documentation, understand the meaning of all the configuration items I wrote, and did not pile up seemingly useful options or default values.
- I provided the complete config and logs, rather than just providing the truncated parts based on my own judgment.
- I searched issues and did not find any similar issues.
- The problem can be successfully reproduced in the latest Release
