Get no last modified timestamp when I request google people api

Question

I want to upgrade my little tool from google contact api to google people api. The authorization is working and I get contacts from peopeService. But the person.Metadata source item array has only one item type "CONTACT". I do miss the 'updateTime' in person.Metadata.Sources. The code snipped:

PeopleResource.ConnectionsResource.ListRequest peopleRequest =
   peopleService.People.Connections.List("people/me");

if (pageToken != null)
{
   peopleRequest.PageToken = pageToken;
}

peopleRequest.RequestMaskIncludeField = 
   person.names,person.organizations,person.birthdays,person.biographies, 
   person.emailAddresses,person.Metadata,person.PhoneNumbers,person.Addresses,
   person.userDefined";
ListConnectionsResponse people = peopleRequest.Execute();

if (people != null && people.Connections != null && people.Connections.Count > 0)
{
   foreach (var person in people.Connections)
   {
      ConvertGooglePerson2ContactItem(person);
   }

   if (people.NextPageToken != null)
   {
      GetAllContactItems(people.NextPageToken);
   }
}

Get Source data:

if (person.Metadata!=null)
foreach (var item in person.Metadata.Sources)
{
...
}

Maybe this is an issue with the query parameters Link. But I don't know how to set this query parameter.

I have tried this API: https://developers.google.com/people/api/rest/v1/people.connections/list

With both fields set: personFields and requestMask.includeField:

400 Bad Request
{
  "error": {
    "code": 400,
    "message": "Please specify only one of requestMask or personFields.",
    "status": "INVALID_ARGUMENT"
  }
}

The result of personFields only please see questions.

The metaData with personFields only of person was given:

      "resourceName": "people/c623380167042605258",
      "etag": "%Eg4BAj0FBwk+Cz8MEEA3LhoEAQIFByIMcG9JRnpDRzBxS0U9",
      "metadata": {
        "sources": [
          {
            "type": "CONTACT",
            "id": "8a6b0f5889920ca",
            "etag": "#poIFzCG0qKE=",
            "updateTime": "2021-01-04T22:44:04.913Z"
          }
        ],
        "objectType": "PERSON"
      },

Maybe it's an API problem?

How can I get last modified time of the people contact?

I'm not sure I fully understand the problem. Using the people.connections.list method you can retrieve the updateTime by default. It is located in the JSON response at connections/metadata/sources/updateTime. — Rafa Guillermo
You can check out this example which uses the Try this API feature to see that the updateTime is returned. — Rafa Guillermo
Also, there are more types than just CONTACT for the person.metadata.source enum. You can see these here. — Rafa Guillermo
@Rafa Guillermo I have added a screenshot of debug session. The Metadata.Source Array contains only one item type "CONTACT". I expect more entries here among others the update time. Is this an issue of the RequestMaskIncludeField or other request parameters? — AndreasU
Where are you specifying the personFields mask for your request? Did you check out the Try This API feature to see if this is reproducible? — Rafa Guillermo

The request is solved with this code snippet:

var updateTime = person.Metadata.Sources.FirstOrDefault().UpdateTime;

Be sure using the Google.Apis.PeopleService.v1 Google APIs Client Library in your project.
