[Bug]: When executing PapyrusUtil's JsonUtil.GetStringValue function, a CTD occurs if an empty character is passed as the third argument.

[oto-git]

Severity

Critical. A critical defect that causes some key functionality to fail.

Priority

High. Anything that impacts the typical user flow or blocks app usage.

Description

I tried calling PapyrusUtil's JsonUtil.GetStringValue function on the SkyrimPlatform side using Papyrus-2-Typescript,
I confirmed that passing an empty string as the 3rd argument causes a CTD.

NetScriptFramework crash log: https://drive.google.com/file/d/1XN70qo_fh6rhPPBU-r7EPtaOSidDewTR/view?usp=sharing

Confirmed that the CTD does not occur when the SkyrimPlatform is version 2.5.
Confirmed that the CTD occurs from version 2.6 (also confirmed that it occurs in version 2.8)

On the papyrus side, running with an empty third argument did not cause any problems.

#1661
Highly relevant bug. This is PapyrusUtil's MiscUtil function, which also generated a CTD when an empty character was specified.
This bug also did not occur in 2.5 but started to occur in version 2.6.

Steps to reproduce

import * as JsonUtil from "../../../Modules/PapyrusUtil/JsonUtil"
once('update', () => {
	let loadFile = "Test.json";
	let test = JsonUtil.GetStringValue(loadFile, 'key1', '');
	printConsole('testJSON:' + test);
});

Assign an empty string to the third argument of JsonUtil.GetStringValue as above and execute.

Expected result

The message 'testJSON:~' appears in the console.

Actual result

CTD occurs during function execution
