Looking for HMR help

@([^

I'm getting an error on an HMR and I really don't understand why?

The error is: Header Rule ReplaceSubscribe (headerName=request-uri action=find-replace-all cmpType=pattern-rule) does not apply to method SUBSCRIBE.

I'm trying to replace the hostname in the To: and the request-uri with an IP address.

The  manipulation is below:
