bcbox/frontend/src/components/common/InviteButton.vue

Line 139 in 15ac109

const emails = isRestricted.value && formData.value.email ? [formData.value.email] : [];

Looks like this line isn't correctly grabbing the email field in the form - formData.value.email returns undefined, so emails never gets populated with the entered email address and the call to the BCBox /email endpoint is never made.

The invite link gets created just fine though.
