EntryPointNotFoundException in some functions of the same .jslib file

Hello people!

I'm trying to use some Javascript functions located in a .jslib file created by my own. This file is located in the Plugins folder as recommended. The project is being built over WebGL.

Here´s the file:

Code (JavaScript):

1. mergeInto(LibraryManager.library, {
2.  
3.   AddNumbers: function (x, y) {
4.     return x + y;
5.   },
6.  
7.   OpenPageInNewTab: function (url) {
8.     url = Pointer_stringify(url);
9.     console.log('Opening link: ' + url);
10.     window.open(url,'_blank');
11.   },
12.  
13.   HideLoadingScreenFadeOut: function () {
14.       let loadingScreen = document.getElementById("loading_screen").querySelector("img");
15.     loadingScreen.classList.add("fade-out-bck");
16.   },
17.  
18.   BindWebGLTexture: function (texture) {
19.     GLctx.bindTexture(GLctx.TEXTURE_2D, GL.textures[texture]);
20.   },
21.  
22. });

And this is the C# class that calls some of those functions:

Code (CSharp):

1. using System.Runtime.InteropServices;
2. using UnityEngine;
3. using UnityEngine.SceneManagement;
4.  
5. public class JavaScriptWebManager : MonoBehaviour
6. {
7.  
8.     [DllImport("__Internal")]
9.     private static extern void HideLoadingScreenFadeOut();
10.  
11.     [DllImport("__Internal")]
12.     private static extern int AddNumbers(int x, int y);
13.  
14.  
15.     void OnEnable()
16.     {
17.        
18.            SceneManager.sceneLoaded += OnSceneLoadedFadeOutLoadingScreen;
19.     }
20.  
21.     private void OnSceneLoadedFadeOutLoadingScreen(Scene scene, LoadSceneMode mode)
22.     {
23.         Debug.Log("LA SUMA DE ADD_NUMBERS ES: " + AddNumbers(4,5));
24.  
25.         HideLoadingScreenFadeOut();
26.     }
27.    
28.     void OnDisable()
29.     {
30.         SceneManager.sceneLoaded -= OnSceneLoadedFadeOutLoadingScreen;
31.     }
32.  
33. }

The thing is, when I call the "OpenPageInNewTab" function in another script, it works perfectly but Unity doesn`t seem to be able to find the "HideLoadingScreenFadeOut" and "AddNumbers" functions in this script.
Unity throws this error when I try to call those functions:

EntryPointNotFoundException: AddNumbers
JavaScriptWebManager.OnSceneLoadedFadeOutLoadingScreen (UnityEngine.SceneManagement.Scene scene, UnityEngine.SceneManagement.LoadSceneMode mode) (at Assets/Scripts/JavaScriptWebManager.cs:30)
UnityEngine.SceneManagement.SceneManager.Internal_SceneLoaded (UnityEngine.SceneManagement.Scene scene, UnityEngine.SceneManagement.LoadSceneMode mode) (at C:/buildslave/unity/build/Runtime/Export/SceneManager/SceneManager.cs:220)

Also, some errors show up when I try to build the project, making the build fail. This errors are related with the previous one I think because they don't appear in the console when I delete the lines related to those functions in the script.


I would like to know why some functions work and some others don't.

Thanks for your help!
