I am trying to connect to an xr device and unfortunately having issues.

options = 'ems.cisco.com'

client = CiscoGRPCClient('x.x.x.x', 57400, 10, 'username', 'password', pem, options) client.getconfig('{"openconfig-interfaces:interfaces": [null]}')

This is throwing alerts as below, Any idea what might be the issue here. Appreciate your help.
