Google Calendar Connector ERROR: Action 'Create_an_event' failed: Bad Request

Hello Community,

I am trying to make an automation the copies, updates or deletes events from outlook to google calendar.

My flow keeps giving the following error on the create, update or delete actions: Action 'Create_an_event' failed: Bad Request

I know that the date is in the correct format because I use this function to format the Outlook date to Google Calendar dates which works for the List the events on calendar action.

formatDateTime(triggerOutputs()?['body/startWithTimeZone'],'yyyy-MM-ddTHH:mm:ss.fffZ')

This is the structure of the flow:

These are the results of two different Google Calendar actions:

Any help or advice would be much appreciated.

Kind regards,
James Abrey.

Hi @JA-11081031-0

Can you share the raw inputs.

Also just curious can you repro the issue here

Syncing Office 365 Outlook to Google calendar using Power Automate

Its just a very simple Google Calendar Event creation sample, shouldn't take long to try.

Hi @Michael E. Gernaey,

Thank you for your reply.

That is a good point about the time. I have tried with other times and get the same result.

Here is another example:

Raw Outputs:

"body": {

        "error": {

            "errors": [

                {

                    "domain": "global",

                    "reason": "badRequest",

                    "message": "Bad Request"

                }

            ],

            "code": 400,

            "message": "Bad Request"

        }

    }

Hi @JA-11081031-0

I notice your start and end times are identical is that on purpose? can't really have an event that starts and ends at the same time.

Can you open the Action up that failed, in the OLD ui please and share that

Thanks!
