Error while adding search head member

[bhupalbobbadi]

Anybody have faced this issue?

$ /opt/splunk/bin/splunk add shcluster-member
Deserialization failed. Could not find expected key 'current_member_uri'

Fresh SH installation, all SH, Master running same version 7.2.0.

Thanks in advance.

Just found the fix.
Instead of adding the new SH to cluster from new Sh, add the new SH from captain SH.

splunk add shcluster-member -new_member_uri <URI>:<management_port>

 that solved the problem.
