amazon web services – AWS Trigger SNS even when there is change in security group


I am trying to send email when there is a change in security group using cloud trail and cloud watch event.

I am using this cloud trail
{ "source": [ "aws.ec2" ], "detail-type": [ "AWS API Call via CloudTrail" ], "detail": { "eventSource": [ "ec2.amazonaws.com" ], "eventName": [ "CreateSecurityGroup", "AuthorizeSecurityGroupEgress", "AuthorizeSecurityGroupIngress", "DeleteSecurityGroup", "RevokeSecurityGroupEgress", "RevokeSecurityGroupIngress", "DescribeStaleSecurityGroups", "DescribeSecurityGroups", "DescribeSecurityGroupReferences" ] } }

Using Input Transformer {"sgroup":"$.detail.requestParameters.groupId","prefixListIds":"$.detail.requestParameters.ipPermissions.items","user":"$.detail.userIdentity.userName","eventname":"$.detail.eventName"}

“Input Path
” / “

“Error Status”
“ErrorCode:”
“ErrorMessage”
“List Of Changes”
“AuthorizeSecurityGroupIngress”
“prefixListIds:”””“

I am receiving email

“”Suhjj RevokeSecurityGroupIngress / sg-hjgjgg”

“Error Status:”

“ErrorCode:”
“ErrorMessage”

“List Of Changes”

“AuthorizeSecurityGroupIngress”

“prefixListIds:”
“[{ipProtocol:tcp,fromPort:22,toPort:22,groups:{},ipRanges:{items:[{cidrIp:0.0.0.0/0}]},ipv6Ranges:{},prefixListIds:{}}]”“

My question is there any way i can remove double quotes”” in between text
