AnonymousEndpoint with address {uri.var.apiurl} in WSO2 EI 6.6 - wso2

Question

I tired to send the request to an endpoint I get the AnonymousEndpoint error and when I hit the endpoint URL with request in the postman it's working fine what should I do to fix this issue.
And I even tired the markForSuspension and suspendOnFailure configuration nothing worked as excepted.
