Notion to Google Calendar error

[Johnny_Wong]

I encountered something quite odd. I created a notion-if-google calendar flow. It executes perfectly during test flow, but the automatic run fails, with the following error message:

"error": {
            "code": 401,
            "message": "Request had invalid authentication credentials. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",
            "errors": [
              {
                "message": "Invalid Credentials",
                "domain": "global",
                "reason": "authError",
                "location": "Authorization",
                "locationType": "header"
              }
            ],
            "status": "UNAUTHENTICATED"

Then I retested the failed data and it succeeded.
I’ve tried reconnecting Google Calendar, but the problem still persists.

I am getting the same message in a filter step when trying to write to a google sheet in the following step. Works sometimes, 4 out of 6 times so far. No idea how to solve it, especially when it is intermittent.
