Kibana interface is not able to hit custom web hook for email notification

Hi Team,

I am trying to send email notification through custom web hook. I have configured monitor, trigger and destination. All are seems to be good but not able to hit the endpoint (the same endpoint I am able to hit from Kibana servers) and there is no error information available in the interface.
When I see in the web console it is showing following error “Refused to execute inline script because it violates the following Content”

Is there any settings or plugins I need to change. Please help me.

Regards,
Sajjith
