fix: new relic code works with urls containing multiple dashes

Description

Fixes the new issue where a user cannot deploy more than once.

The error occurred when the domain contained multiple dashes, breaking the split.

In addition, I've added some error handling code to print the response when there is an error on the new relic api.
