Microsoft-graph-docs: Create appRoleAssignment does not work.

[andrewfabrizi]

This API method returns the following:
{
"error": {
"code": "Request_BadRequest",
"message": "One or more properties are invalid.",
"innerError": {
"request-id": "6ab3a024-2078-40fe-8460-50f3dcf589b8",
"date": "2019-08-26T13:39:52"
}
}
}

        const string ROLE_ASSIGNMENT_FORMATTER = "https://graph.microsoft.com/beta/servicePrincipals/{0}/appRoleAssignments";

        public static async Task AddApplicationUsers(string enterpriseAppId, string userId, string roleId)
        {
            HttpClient client = new HttpClient();
            string url = string.Format(ROLE_ASSIGNMENT_FORMATTER, enterpriseAppId);

            client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", await GetAccessToken());

            var roleAssignment = new
            {
                appRoleId = roleId,
                principalId = userId,
                resourceId = enterpriseAppId
            };


            var content = new StringContent(Newtonsoft.Json.JsonConvert.SerializeObject(roleAssignment), Encoding.UTF8, "application/json");
            content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
            var response  = await client.PostAsync(url, content);

            if (response.IsSuccessStatusCode)
            {
                return ;
            }
            else
            {
                throw new HttpRequestException(response.ReasonPhrase);
            }
        }
