This is the path - cdn-cgi/bm/cv/2172558837/api.js of the js which is being showin by cloudflare on my site. I have tried enabling and disabling many options.
Google page speed score is really low because of this JS.
I am using free plan.
I have already mailed cloudflare support.
These are some other community threads with the same issue
They sent me a reply.
"Any script with the endpoint /cdn-cgi/ are cloudlfare internal endpoint. All Cloudflare zones have a set of /cdn-cgi/* paths on them that instead of routing to the clients website, will be redirected to a function. These functions print debugging information, or handle a request in a special way. There is no way to disable /cdn-cgi/* pages.
We use this path to serve multiple items e.g. - /cdn-cgi/images/retry.png is the retry button background for the Always Online banner or the endpoint /cdn-cgi/styles/cf.errors.css is the CSS styles for our error pages."
