Hello Make Support Team,
I am experiencing a blocking issue in a scenario that should create a Google Calendar event from an incoming email.
• Google account used (Make connection): mr…@gmail.com
• Target calendar: Semaines disponibles (Make shows the long technical ID: 960639d71fa64a9b29f5575be418b11b9…)
• Scenario chain: Email (Watch Emails) → Google Calendar (Create an Event) → Google Calendar (Create an Event)
• Scenario URLs in my browser:
• https://eu2.make.com/…/scenarios/6866212/edit
• https://eu2.make.com/…/scenarios/2519589/edit (two versions during my tests)
• Timezone: Europe/Paris
⸻
1) Google Calendar module error (right side of the scenario)
During execution, I get a red error block with:
[404] … /calendar/v3/calendars/events (Requested URL not found)
The failing module is the Google Calendar → Create an Event on the far right (icon 31 with red exclamation mark).
Note: The Calendar ID is correctly selected in the list (it shows a long alphanumeric string, which is normal). The calendar “Semaines disponibles” belongs to the account mr…@gmail.com.

2) Cannot validate Start/End Date fields
In Start Date / End Date, I do not see the fx button.
When I type date functions, Make always returns:
“Value is not a valid date.”
Tests I tried (with and without spaces, using semicolon ; and comma , depending on locale):
• now() → Value is not a valid date
• formatDate(now(); “YYYY-MM-DDTHH:mm:ssZ”) → Value is not a valid date
• formatDate(now(), “YYYY-MM-DDTHH:mm:ssZ”) → Value is not a valid date
• formatDate(addHours(now();1); “YYYY-MM-DDTHH:mm:ssZ”) → Value is not a valid date
• formatDate(addHours(now(),1), “YYYY-MM-DDTHH:mm:ssZ”) → Value is not a valid date
I also tried leaving End Date empty and using Duration (01:00) → same validation issue on Start Date.
⸻
3) What I expect
• Confirmation of the exact date format accepted by the Start/End Date fields in Google Calendar → Create an Event (and which separator is expected for an account in French locale: ; vs ,).
• Why the Start Date field does not show the fx button (so I cannot clearly switch into “expression mode”), while other fields show “Map.”
• Verify in Make logs why the API call fails with 404 /calendars/events (suggesting maybe calendarId is not passed?), even though the calendar ID is correctly selected.
• Any recommendation/fix so that I can set a dynamic date (e.g., now() + 1h) without the “not a valid date” error.

4) How to reproduce
1. Open the scenario → Google Calendar – Create an Event (last module on the right).
2. Connection: mr…@gmail.com
3. Calendar ID: select Semaines disponibles (long alphanumeric ID).
4. Event Name: map the email Subject.
5. Start Date: try formatDate(now(); “YYYY-MM-DDTHH:mm:ssZ”) (or version with comma). → rejected.
6. End Date: try formatDate(addHours(now();1); “YYYY-MM-DDTHH:mm:ssZ”) (or version with comma). → rejected.
7. Run once → sometimes 404 error on Google Calendar API.

I can provide screenshots showing:
• Start/End fields in red,
• 404 error block,
• Calendar ID list,
• Current mapping.
