I am not able to add google meet to a calendar event api using nodejs

I am using google APIs to create an event and add a google meet link to that event.

Calendar event creation is working fine but I am not able to add a google meet link

 const response = await calendar.events.patch({
    auth: auth,
    calendarId: calendarId,
    eventId: "6df3sea0jhl6tueoos4qjr41a0",
    requestBody: {
      conferenceData: {
        createRequest: {
          requestId: "asdafas14",
        },
        conferenceSolution: {
          key: {
            type: "hangoutsMeet",
          },
        },
      },
    },
    sendNotifications: true,
    conferenceDataVersion: 1,
  });

With the above payload, the response is 200 but no meeting link was added

Also tried this by changing payload

await calendar.events.patch({
    auth: auth,
    calendarId: calendarId,
    eventId: "6df3sea0jhl6tueoos4qjr41a0",
    requestBody: {
      conferenceData: {
        createRequest: {
          requestId: "asdafas14",
          conferenceSolutionKey: {
            type: "hangoutsMeet",
          },
        },
      },
    },
    sendNotifications: true,
    conferenceDataVersion: 1,
  });

Response is 400 and gives the errors

 {
      domain: 'global',
      reason: 'invalid',
      message: 'Invalid conference type value.'
    }

I am using a developer service account from https://console.cloud.google.com/apis/dashboard

Can anyone please help me with what is wrong here? Thanks in advance

I made it work with a few changes to your code, the the following example:

  const response = await calendar.events.patch({
        auth: auth,
        calendarId: calendarId,
        // I replace my event ID for yours
        // so you can only copy and paste it on your code. 
        eventId: "6df3sea0jhl6tueoos4qjr41a0",
        requestBody: {
            "conferenceData": {
                "createRequest": {
                  // place "conferenceSolutionKey" inside "createRequest"
                    "conferenceSolutionKey": {
                        "type": "hangoutsMeet"
                    }, 
                    // change the request of the requestID
                    "requestId": "sample1234"
                },
            },
        },
        sendNotifications: true,
        conferenceDataVersion: 1,
    });
    console.log(response.data.hangoutLink);
