Error text
Error in deployment for environment test. The revision is deployed, but traffic cannot flow. Error while fetching children for path
If the message includes the words traffic cannot flow, it means that the proxy could not be deployed to ANY available Message Processors or Routers.
If the message says traffic can flow, but flow may be impaired, it means the proxy might have been deployed to some, but not to all available Message Processors or Routers (a partial deployment).

Cause

Force undeploy and redeploy
