OK, so now it looks like this
import { appendValuesWrapper } from ‘backend/googlesheet-wrapper.jsw’ ;
export function wixEvents_onRsvpCreated ( event ) {
const eventId = event . eventId ;
const rsvpId = event . rsvpId ;
const status = event . status ;
const firstName = event . firstName ;
const lastName = event . lastName ;
const email = event . email ;
const rsvp = event . rsvpForm ;
const comment = event . comment ;
const values = [ firstName , lastName , email ];
const res = appendValuesWrapper ( values );
}
That works as expected and I get the values from the Event RSVP form populating my Google Sheet.
However there is a fields called rsvpForm as “documented” here onRsvpCreated - Velo API Reference - Wix.com
Those are the values that I really want.
