GoogleApiException: Parameter "spreadsheetId" is missing

Hey everyone, I'm trying to access Google Spreadsheets API in my app. But i have ran into a problem on the il2cpp Android build of my app.

 using System.Collections.Generic;
 using UnityEngine;
 
 using Google.Apis.Auth.OAuth2;
 using Google.Apis.Sheets.v4;
 using Google.Apis.Services;
 using Google.Apis.Sheets.v4.Data;
 using System.Security.Cryptography.X509Certificates;
 
 using System.Text;
 using TMPro;
 public class GoogleSheetsTest : MonoBehaviour
 {
 
     public TextMeshProUGUI text;
 
     string p12PathFromAsset;
 
     
     const string sheetNameAndRange = "A!A1:D13";
     const string serviceAccountEmail = "MY_SERVICE_ACCOUNT";
     static SheetsService service;
 
     private void Awake()
     {
         RequestPath();
     }
 
     void RequestPath()
     {
         string keyPath = "P12_KEY_LOCATION";
         string realPath;
 
         if (Application.platform == RuntimePlatform.Android)
         {
             // Android
             string oriPath = System.IO.Path.Combine(Application.streamingAssetsPath, keyPath);
 
             // Android only use WWW to read file
             WWW reader = new WWW(oriPath);
             while (!reader.isDone) { }
 
             realPath = Application.persistentDataPath + "P12_KEY_STUFF";
             System.IO.File.WriteAllBytes(realPath, reader.bytes);
 
             Debug.Log("Running Android");
 
             p12PathFromAsset = realPath.Replace("p12",".p12");
         }
         else
         {
             // iOS
             p12PathFromAsset = System.IO.Path.Combine(Application.streamingAssetsPath, keyPath);
         }
 
         SyncData();
 
     }
 
     void SyncData()
     {
 
         var certificate = new X509Certificate2(p12PathFromAsset, "notasecret", X509KeyStorageFlags.Exportable);
 
         text.text = p12PathFromAsset;
 
         ServiceAccountCredential credential = new ServiceAccountCredential(
            new ServiceAccountCredential.Initializer(serviceAccountEmail)
            {
                Scopes = new[] { SheetsService.Scope.Spreadsheets }
                /*
                 Without this scope, it will :
                 GoogleApiException: Google.Apis.Requests.RequestError

                 2 access token, login cookie or other valid authentication 
                 credential.
                 lol..
                 */
            }.FromCertificate(certificate));
 
         service = new SheetsService(new BaseClientService.Initializer()
         {
             HttpClientInitializer = credential,
         });
 
         string spreadsheetid = "MY_SPREADSHEET_ID";
         var request = service.Spreadsheets.Values.Get(spreadsheetid, sheetNameAndRange);
 
         StringBuilder sb = new StringBuilder();
 
         ValueRange response = request.Execute();
         IList<IList<object>> values = response.Values;
         if (values != null && values.Count > 0)
         {
             foreach (IList<object> row in values)
             {
                 foreach (object cell in row)
                 {
                     sb.Append(cell.ToString() + " ");
                 }
 
                 //Concat the whole row
                 Debug.Log(sb.ToString());
                 text.text = sb.ToString();
 
                 sb.Clear();
             }
         }
         else
         {
             Debug.Log("No data found.");
         }
     }
 }    

It's a simple script that gets the Google Sheet with the "MY_SPREADSHEET_ID", then authorises my access via "MY_SERVICE_ACCOUNT" , with the p12 key linked to the service account. The script has no problems, running on Editor. On Android i can access the p12 path and i dont think i have auth issues. But when i run it i get this exception on Android Logcat:

I have no idea what could be causing this exception since it can perfectly read and get data from the spreadsheet on Editor. I tried a const string variable, getting rid of the variable and just typing the string to the method field. I tried to search online but it seems nobody has this problem but me.

Thanks in advance.
