Description

If you forget to configure a host name then the rest producer fails with different errors if you use http4, netty4-http, undertow etc.

We should likely add some validation logic in the rest endpoint / rest producer so it can detect this missing configuration and report this in the same way.

You can reproduce from this example by removing host at
