Getting Error while enabling Stats for wso2 esb API and EndPoint

Question

I have enabled Stats for my API and Endpoints from Enterprise Integrator Dashboard. I have also made true following properties in /conf/synapse.properties as given below.

mediation.flow.statistics.enable=true
mediation.flow.statistics.tracer.collect.payloads=true
mediation.flow.statistics.tracer.collect.properties=true
mediation.flow.statistics.collect.all=true

Then I have started Enterprise Integrator Analytics Dashboard 6.6.0 and Started Server from Integration studio which deploys my two applications. It gives me an Integrator Dashboard URL as given https://192.168.0.75:9443/carbon/

I have moved to the EndPoints section and API section and Enable Tracing and Enable Statistics from there. Then have Open Analytics dashboard using URL as given below. https://192.168.0.75:9643/portal

But I did not find any data then. then I again request from the postman and I find some errors in my as a console as given below.

Below is the point which I follow and It's working for me. 1. Check TCP and SSL Port in Carbon.XML in your ESB Integrator Directory config.

Check the same ports in Integrator Directory_Version(6.6.0) \repository\deployment\server\eventpublishers. There you find two files named MessageFlowConfigurationPublisher and MessageFlowStatisticsPublisher Check the same TCP AND SSL port the same as above given under Analytics in Carbon.xml.
Make Given property as true ..Mention in Question above.
Then first Start your Analytics Worker
Start your Analytics Dashboard
At last start, Your ESB server, which runs your wso2 ESB application. It will give your carbon home URL (integrator dashboard URL). In that enable stats and tracking for all API's and endpoints and at last hit one of your API.
Take the Analytics Dashboard URL from Point 5 work and login with admin/admin.
You can able to see stats and tracing there.
