# Ohayo! RimuruDev here 😃

The warning you’re encountering is related to the deprecated use of the `Pointer_stringify` function in Unity WebGL. This warning should not prevent your game from working by default, but it does indicate that a deprecated function is being used in Unity scripts, which will be removed in future Unity versions.

The errors look like this:

```auto
Pointer_stringify(ptrToSomeCString)

```

or

```auto
The JavaScript function 'Pointer_stringify(ptrToSomeCString)' is obsoleted and will be removed in a future Unity version. Please call 'UTF8ToString(ptrToSomeCString)' instead. 

```

## **Here’s how you can fix it** :

**1. Updating Unity code** :

- Find all occurrences of `Pointer_stringify` in your Unity project’s code.
- Replace them with `UTF8ToString`, as recommended in the error message.

**2. Updating plugins or assets** :

- If this warning arises from external assets or plugins, check for updates that might resolve this warning.

### But how do you find where you used Pointer\_stringify? 🤔

**And if you didn’t use Pointer\_stringify, then how to determine where it is currently used? 🤔**

→ First - open the IDE with your project solution. Or click as shown in the picture:

→ Next are examples on Rider but it works similarly in any IDE, although the hotkeys may differ. My IDE is Rider with the IntelliJ Keymap:

→ Press the `ctrl + shift + f` combination, and a window will appear where you need to enter the name of the old function as shown below:

→ Click on the shown options and replace Pointer\_stringify with UTF8ToString as shown in the screenshot. I highlighted the old function name Pointer\_stringify and simply pasted UTF8ToString in its place.

In my case, since I never used Pointer\_stringify anywhere, Rider indicated that the only calls are found in the file `UnityWebSocketBridge.jslib`, which is a JavaScript library used in Unity WebGL projects for interacting with web sockets.

I also made changes to it. And the error disappeared.

Once you’ve replaced all calls to Pointer\_stringify functions with UTF8ToString in your project, save the project and rebuild it.

That’s it! This should help you solve your problem.

I translated this text from Russian to English. My English isn’t great, but I hope at least the screenshots make it clear how to solve your problem.

❤ Wishing you all the best ❤

Hi @RimuruDev , I got this issue in my webgl build while connecting socket - ReferenceError: Pointer\_stringify is not defined at \_NKCreateSocket .

code : await \_Socket.ConnectAsync(\_Session, appearOnline, connectTimeout, langTag);
