RangeError: Internal error. Icu error.

[xtroncode]

Hi, I am using ReactJS.net (v5.2.5) with JavaScriptEngineSwitcher.V8 (v3.12.5) in .netcore 3.1 with

<PackageReference Include="Microsoft.ClearScript.V8.Native.linux-x64" Version="7.1.6" />
<PackageReference Include="Microsoft.ClearScript.V8.Native.win-x64" Version="7.1.6" />

and I am getting the following exception while using toLocaleString in my script

RootComponent root

Here is a reproduction of the error https://github.com/xtroncode/jsengineswitcher-chakracore-issue/tree/jsengineswitcher-v8-issue

Let me know if I can provide any more information

Thanks.

Hello, Meet!

I can't reproduce this error. It is possible that I have different regional settings on my computer.

First, try updating the JavaScriptEngineSwitcher.V8 package to the latest version (3.13.1).

If this does not help, then try to additionally install the Microsoft.ClearScript.V8.ICUData package.

Ok. Thanks. I'll try and let you know.

Installing the Microsoft.ClearScript.V8.ICUData package fixes the issue. Thanks a lot.
