The returned Operation type has the following method-specific fields: -
metadata: CreateConversationModelOperationMetadata - response:
ConversationModel

this method will complete with the same error.
Implementation
async.Future<GoogleLongrunningOperation> create(
  GoogleCloudDialogflowV2ConversationModel request,
  core.String parent, {
  core.String? $fields,
}) async {
  final body_ = convert.json.encode(request);
  final queryParams_ = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };
  final url_ = 'v2/' + core.Uri.encodeFull('$parent') + '/conversationModels';
  final response_ = await _requester.request(
    url_,
    'POST',
    body: body_,
    queryParams: queryParams_,
  );
  return GoogleLongrunningOperation.fromJson(
    response_ as core.Map<core.String, core.dynamic>,
  );
