console errors

What steps have you taken to resolve the issue?

I am getting server side errors in Google Console atleast one every couple of days with this url https://brisbanekids.com.au/cdn-cgi/rum. My developer is unavailable and my host server (big reputable company has told me to ignore it). I am concerned about just letting errors like this go on as I am getting alerts from google about it.
I have trawled the groups and the suggestion is just to use a robottxt to block google bots from reach things with the path /cdn-cgi/rum - is this going to impact anything if I do this? Or am I thinking about this in totally the wrong way.

What are the steps to reproduce the issue?

You can use robots.txt to discourage indexing the entire /cdn-cgi/ path altogether. There is nothing there that needs to be crawled. It is considered best practice to have such an exclusion.

Thanks- I will give that a go.

Since Cloudflare adds and manages the /cdn-cgi/ endpoint, it makes more sense to address this on their side with a X-Robots-Tag: noindex, nofollow response header.

Adding this header via a custom Response Header Transform Rule does not work, since (again) Cloudflare manages this endpoint and does not allow any alterations (which makes sense).
