SecurityError: blocked a frame with origin "https://www.google.com" from accessing a frame with origin "<your domain>"
This typically occurs if the reCAPTCHA widget HTML element is
programmatically removed sometime after the end user clicks on the checkbox.
We recommend using the grecaptcha.enterprise.reset()
JavaScript function to reset the reCAPTCHA widget.
Localhost is not in the list of supported domains
Localhost domains are not supported by default. If you want to continue
supporting them for development, you can add them to the list of supported
domains for your site key.
Go to the Google Cloud console
to update your list of supported domains. We advise to use separate keys for
development and production, and to only allow localhost on your development site
key.
reCAPTCHA returned BROWSER_ERROR when creating an assessment
BROWSER_ERROR tokens occur when the reCAPTCHA script cannot perform
an execute operation. In most cases, this is due to a client-side network
failure or timeout. You must retry execute() using the JavaScript.
