Hi
*Issue:*
Getting following error while expanding server group node.
File
"/Users/surinder/Documents/Projects/pgadmin4/web/pgadmin/browser/server_groups/servers/__init__.py",
line 86, in get_nodes
in_recovery = result['rows'][0]['inrecovery'];
TypeError: string indices must be integers
Not a proper scenario to reproduce it.
*Solution:*
Add proper check to fix it.
