Cannot use hCaptcha with forms that have file uploads such as Divi Contact Form

[angelsvirkov]

Some forms such as Divi Contact Form have the possibility to upload a file with the form. While doing so, the underlying code might already send an ajax request, which would trigger the ajaxSuccess event with some arbritrary settings.data type. It looks like the JS assets at ./assets/js/1595567093/hcaptcha-divi.js define an event listener which strictly expects that the settings.data has a callable property includes. The latter is not correct in the case of the file uploads. Therefore, the hCaptcha behaviour crashes and the whole form cannot be submitted.

Steps to reproduce

• Try to trigger an ajaxSuccess event where the settings.data is not a string but an object instead or
• Use a form with file upload (e.g. Divi Contact Form) and upload a file to the form. The whole form will be stuck because of an uncaught exception

Uncaught TypeError: settings.data.includes is not a function
    at HTMLDocument.<anonymous> (hcaptcha-divi.min.js?ver=3.10.1:8:19)
    at HTMLDocument.dispatch (jquery.min.js?ver=3.7.1:2:40035)

I will try to submit a PR to fix this as it looks as a minor type guarding issue. -> My attempt to solve the issue https://github.com/hCaptcha/hcaptcha-wordpress-plugin/pull/326

Thank you, @angelsvirkov, for the report and the PR; it is appreciated!

I do not have the Divi Contact Form Helper plugin for testing. Could you share a zip file via email to info@kagg.eu?

I have changed the issue name. It is not a bug but an enhancement. Our code does not support so far the premium plugin Divi Contact Form Helper.

@angelsvirkov, thank you for providing the plugin for testing. I have fixed the issue in this commit.

Great, thanks. Is there any roadmap or plan for the release of v4?
