What is the error message?

Blocked script execution in ‘about:blank’ because the document’s frame is sandboxed and the ‘allow-scripts’ permission is not set.

What is the issue you’re encountering

Repeated error message observed in browser console in batches of 10. No non-interactive solves happened.

What are the steps to reproduce the issue?

Visit any site which is using turnstile on Edge or Chrome and look at the browser console. In many sites, it looks like non-interactive challenges fail multiple times. Sometimes it validates in the end, sometimes it requests the checkbox to be clicked. On our in development privately accessible domain, it never did a non-interactive solve.

When the checkbox was left unclicked, it kept trying to auto verify every few minutes, however it always failed to auto verify (non-interactive solve).

Similar observation in firefox as well, however no errors were visible in its console.

The issue seems to have been caused by the presence of a certain browser extension. The extension was enabled both in Chrome and Edge. Upon disabling the extension, the error was not observed anymore.

The no ‘non-interactive’ solves may be attributed to our use of VPN to access the private development and staging environments. Few ‘non-interactive’ solves were observed when allowing use outside of the VPN.
