Custom Action: sending Date to Zapier

I am trying to create a custom action to send dates to Zapier and then create a Google Calendar invite. I am having trouble with the date format. In the custom action workflow in Adalo I am creating the test date format as “2020-09-16” but in Zapier the date turn into a number, like “18522”. Is this an issue with the test date format when setting up the custom action in Adalo?

Zapier has a date and time formatter. Try adding an extra step before the Google Calendar action to format the date and time. That should work
