 Deploying a Radius Application that contains a gateway resource and a container resource that share a name will result in an error being thrown during the deployment process.
 
+```
+Error - Type: IncludeError, Status: True, Reason: RootIncludesRoot, Message: root httpproxy cannot include another root httpproxy
+```
+
 As a workaround make sure to use distinct names for both containers and gateways.
