Description

Google Calendar connector action ‘Update Event’ doesn’t allow partial update of an event.

This issue applies to a use-case where Update Event is used on its own, not depending on a data input from preceding step, e.g. timer -> ‘Update event’.

When user specifies calendar and eventId, and changes only ‘location’ in the form, I would expect, that only that single field is being attempted to be updated.

Pre-filling values into the form is not a valid solution, as it is valid only design time, not during runtime (event could have been updated meanwhile). Rather we’d need to handle the form input as a selective update, see https://developers.google.com/calendar/v3/reference/events/patch .

To illustrate the issue, what I see is, that event the date/time fields are being attempted to be updated even though I set only ‘location’ in the form. The error I get:
