### GCSFuse crashes with `fatal error: sync: unlock of unlocked mutex` or `Panic: Inode 'a/' cannot have child file ''`

**Solution:** This happens when bucket contains an object with suffix `/\n` like, `gs://gcs-bkt/a/\n`
You need to find such objects and replace them with any other valid gcs object names. - [How](https://github.com/GoogleCloudPlatform/gcsfuse/discussions/2894)?

instead of gcs object names should it be file system names names.
And there is nothing mentioned about how to replace them.
