The following log message seems to be cut off

"TypeError: Cannot read property 'length' of undefined\n at

Can you post the entire log line? There should be a stack trace which might help pinpoint the problem.

Regards,

Sorry! Here is the full log.

Unfortunately that stack trace isn't very helpful. It appears as if it's an error in a dependency we use to delete files.

Can you run Kibana with --verbose and post the logs?

Hi Rudolf!

I had to delete the cluster because it was installed on LXC, and there was no way to recover the cluster.
Fortunately, it was only a testing environment.

I have installed the 7.6 version on centos in a virtual machine, and I haven't had an issue.

Thanks for your support.

Good to hear that you came right :slight_smile:
