Cannot commit in mercurial repo

问题:

I have a Mercuirial (3.6.1) project. Every time I try to commit I get the next error.

(project)➜  project hg:(default) ✗ hg commit -m "TICK-190" subfolder/models.py

There's no much more detail I can explain. I was commiting my code without problems and suddenly this error started to show. I cannot commit any file. I can ask gor hg status with no problem.

Since this is a legacy project I've recently got, I want to make as little changes as possible.

UPDATE:

hg verify

You may have found a bug in Mercurial, but try updating to the latest Mercurial version (3.9) first before you file a bug report. https://www.mercurial-scm.org

Re:Update: That looks like your repository is faulty. Maybe your hard drive has errors? Is this the only copy of the repository, or is there another one somewhere else? You best bet is probably to try and find a non-broken copy.
