This error may appear if your website has a Content-Security-Policy header that is too restrictive.

This header caused the "Mismatch token" error for me:

content-security-policy: default-src 'self'; style-src 'self' 'unsafe-inline';

By adding script-src 'self' 'unsafe-inline'; the error disappeared:

content-security-policy: default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline';
