What was reported:
Issue cloudflare/cloudflare-docs#30360 (closed, 26 comments): Turnstile's invisible mode generates a large volume of console errors and warnings that are entirely internal to the challenges.cloudflare.com iframe. While these don't block functionality, they spam the developer console and create confusion for developers and QA teams who see a 'wall of red' on every page load. Errors observed, all from challenges.cloudflare.com: '[Violation] Permissions policy violation: xr-spatial-tracking is not allowed in this document' (repeated ~20x), TrustedHTML assignment warnings, CSP violations.
What works:
Turnstile invisible mode spams the console with errors from the challenges.cloudflare.com iframe (permissions policy violations, TrustedHTML warnings, CSP violations). These are internal Turnstile noise and don't affect functionality or performance, so a wall of red in the console is not a broken integration. Cloudflare reduced most of the noise already; updating to the newest Turnstile build cuts down the volume further.
