Hi all,

and from Splunk Web:

"Unexpected error occurs. In handler 'splunk_app_aws_proxy_inputs': Unexpected error "" from python handler: "HTTP 404 Not Found -- In handler 'roles': Could not find object id=winfra-admin". See splunkd.log for more details."

what is the cause and how i can solve it?

Thanks!
