Capture Screenshot not working in WebGL

I tried making a script that uses the main camera to take a screenshot of the object. It works well in unity without any errors but I tried to build it as a WebGL. Sadly, it shows an error that tells me to enable the exception to know it. Enabled it and didn't figure out anything at all. Is there something I missed with the WebGL coding? Any help would be appreciated. Thank you!

 using UnityEngine;
 using System.Collections;
 
 public class ScreenCapture : MonoBehaviour {
     public int resWidth = 960; 
     public int resHeight = 600;
 
 
     public static string ScreenShotName(int width, int height) {
         return string.Format("C:/PerfLogs/screen_{1}x{2}_{3}.png", 
             Application.dataPath, 
             width, height, 
             System.DateTime.Now.ToString("yyyy-MM-dd_HH-mm-ss"));
     }
         
 
     public void ScreenshotButton() {
             RenderTexture rt = new RenderTexture(resWidth, resHeight, 24);
             GetComponent<Camera>().targetTexture = rt;
             Texture2D screenShot = new Texture2D(resWidth, resHeight, TextureFormat.ARGB32, false);
             GetComponent<Camera>().Render();
             RenderTexture.active = rt;
             screenShot.ReadPixels(new Rect(0, 0, resWidth, resHeight), 0, 0);
             GetComponent<Camera>().targetTexture = null;
             RenderTexture.active = null; // JC: added to avoid errors
             Destroy(rt);
             byte[] bytes = screenShot.EncodeToPNG();
             string filename = ScreenShotName(resWidth, resHeight);
             System.IO.File.WriteAllBytes(filename, bytes);
             Debug.Log(string.Format("Took screenshot to: {0}", filename));
             Debug.Log("Screenshot Saved!");
         }
 
 
 }

Here's a picture of the error.
