getting commR: commr is nil

[uranuschen365]

I use "lotus-miner proving check --only-bad" command show this error
1 0 5442 bad (getting commR: commr is nil)
1 0 3785 bad (getting commR: commr is nil)
1 0 3605 bad (getting commR: commr is nil)
1 0 5345 bad (getting commR: commr is nil)

This is my miner log:

this mean the commR value in lotus miner is nil.

To troubleshoot this issue, you can try the following steps:

1. check you are using the lotus latest version!
2. Check sector sealing process
3. Examine storage configurations
4. Validate the sector data
5. Review your miner configuration

already if you still get the error, you can open an issue about it or check for existing issues.
