OAuth Token Request Returns a Truncated Token

The access_token is always 632 characters long, and when I test it in Postman it works fine

Postman Code:

using System;
using RestSharp;
namespace HelloWorldApplication {
  class HelloWorld {
    static void Main(string[] args) {
      var client = new RestClient("https://zoom.us/oauth/token?account_id=VfdA06Q9TQe31jH7oRutuQ&grant_type=account_credentials");
      client.Timeout = -1;
      var request = new RestRequest(Method.POST);
      request.AddHeader("Authorization", "Basic ####");
      request.AddHeader("Cookie", "####");
      var body = @"";
      request.AddParameter("text/plain", body,  ParameterType.RequestBody);
      IRestResponse response = client.Execute(request);

I have a limitation that prevents me from using RestSharp. As such, I am using System.Net.Http in my application, but the access_token is always 533 characters long. I get unauthorized response whenever I use that token which is what alerted me that something may be wrong with it.

System.Net.Http Code

using System;
using System.Collections.Generic;
using System.Net.Http;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;

namespace ConsoleApp_Test_ZoomCreateMeeting
    class Program
        static void Main(string[] args)
            //Get current token age
             // Get the get credentials

            // Build the request body
            var authRequestBody = new FormUrlEncodedContent(new[]
            new KeyValuePair<string, string>("grant_type", "client_credentials"),
            new KeyValuePair<string, string>("client_id", "####"),
            new KeyValuePair<string, string>("client_secret", "####")

            // Set up the HTTP client
            var authClient = new HttpClient();
            authClient.BaseAddress = new Uri("https://zoom.us/");

            // Send the request and get the response
            HttpResponseMessage authResponse = authClient.PostAsync("oauth/token", authRequestBody).Result;

            string content = authResponse.Content.ReadAsStringAsync().Result;
            long contentLength = authResponse.Content.Headers.ContentLength ?? 0;

            string responseContent = authResponse.Content.ReadAsStringAsync().Result;

            // Parse the JSON response
            JObject jsonResponse = JsonConvert.DeserializeObject<JObject>(responseContent);

            // Create an instance of JsonSerializerSettings and set the ReferenceLoopHandling property to Ignore
            JsonSerializerSettings serializerSettings = new JsonSerializerSettings();
            serializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;

            // Serialize the jsonResponse object using the JsonSerializerSettings object
            string serializedJsonResponse = JsonConvert.SerializeObject(jsonResponse, serializerSettings);

            // Extract the access_token property (value<t>)
            string currentToken = jsonResponse["access_token"].Value<string>();           

            Console.WriteLine("Current Token: " + currentToken);        


Any ideas on a solution here?

I tried to request an OAuth token from the Zoom API, and though I received one, the access_token attribute is being cut short
