Hi @Elcio_Bernardo_Souto and welcome to the community

If I understand you correctly you have a problem with this code when testing locally. In Firefox you can open about:config and switch security.fileuri.strict_origin_policy to true.
This will disable CORS for “file:///” URIs. Please be aware that turning off this feature can lead to security problems. (Bugzilla 1558299)

I hope that helps!

Happy coding,
Michael

Boa tarde a todos,pra quem tem a mesma duvida,em vez de desabilitar o CORS,podes instalar um servidor python local e correr os exemplos localmente,
