Error when opening LCM via PRISM

After the upgrade to AOS 5.1.5, my LCM console gave the following message.

Error_LifeCycleManager
Error message
You can solve this issue by doing the following steps:

1). Verified that the PRISM shows: JSON RPC request error.

2). verified from ~$ zkls /appliance/logical/pyleaders/lcm_leader/  one of the CVM was not listed. I have 9.
n_0000000096
n_0000000097
n_0000000098
n_0000000099
n_0000000100
n_0000000101
n_0000000102
n_0000000103

3). Verified One of the CVM .101 has .genesis_restart_required_path file.
~$ allssh "ls -latr ~/.genesis_restart_required_path"

4). Removed the file and restarted genesis on all the CVMs.
~$ rm .genesis_restart_required_path
~$ allssh genesis restart

5). Verified the issue does not exist anymore.
