Hi

I'm following the Kubernetes tutorial in the Academy to deploy the Exchange service:

https://academy.creatio.com/documents/administration/7-16/deploying-synchronization-service-kubernetes?document=administration#CSH_3

I deployed Redis database and ExchangeListener package using Helm.

When I deployed the ExchangeListener package and forwarded the local port to the host I got "Connection Refused" and the service crashed.

Any help! 

PS C:\Windows\system32> helm install --set apiVersion=apps/v1 --set env.host=exchange-listener-redis-master.default.svc.cluster.local --name creatioexchangelistener "C:\Program Files\kubernetes\exchangelistener-0.5.0.tgz"

Hello

I'm deploying Creatio Exchange Listener for my developing environment. 

I'm following this academy guide:

https://academy.creatio.com/documents/administration/7-16/deploying-synchronization-service-docker?document=administration#CSH_4

I got this error message when I created the listener container:

I tested the service and its working:

{

}

I made the creatio configuration side:

Now, I can send emails but when I try to sync the mailbox I got this error:

How to apply access permissions (object permission) / access right when insert data via server-side?

I have set the record access permission, but when inserting via server-side, the access right does not work. The insert method that I did was in accordance with the article above.

Thanks.
