Someone added a Tag to our page (within the business) which caused an ad to stop displaying (marketing went into a spin!).
The error shown in Chrome's console was:
Failed to execute 'write' on 'Document': It isn't possible to write into a document from an asynchronously-loaded external script unless it is explicitly opened.
Does anyone know how I can measure these errors to alert us to the fact that something is failing on the page. I added an error rule but think that may only work if using the browser agent.
