I’m also experiencing the same problem using Hubspot’s recommended method of introducing a change event
hbspt.forms.create({
portalId: “xxxxxxx”,
formId: “xxxxxxx-xxxxxxx-xxxxxx-xxxxxx”,
onFormReady($form) {
$(‘input[name=“email”]’).val(emailAddress).change();
}
});
And return the error
http://js.hsforms.net/forms/v2.js: Uncaught TypeError: Cannot read property ‘target’ of undefined
Some HS developer support would be appreciated, as many people seem to be experiencing this same issue.
