"NullReferenceException: Object reference not set to an instance of an object" when converting Niagara uasset files back from json.

[RiccTheThicc]

Describe the bug
Trying to open the exported json file results in an error: "Encountered an unknown error when trying to open this file! System.NullReferenceException: Object reference not set to an instance of an object."
This issue is very similar to closed issue #91, which was solved by allowing an object be set to null. My guess is a different object is being set to null here.

To Reproduce
Steps to reproduce the behavior:

1. Open "NS_JumpPad.uasset"
2. Save as "NS_JumpPad.json"
3. Open "NS_JumpPad.json"
4. See error

Unmodified uasset file: NS_JumpPad.zip

Expected behavior
When converting to .json, you should be able to reopen the json in UassetGUI to convert back to uasset.

Screenshots

Desktop:

• OS: Windows 11
• Version or Commit: UAssetGUI v1.0.2 (eea59f3 - 46c4fbf). Not sure what UAssetAPI version the gui uses, but the github page said to report these kinds of errors here instead of on UAssetGUI's issues page.

Additional Context
The .uasset file is from Islands of Insight, and was cooked with Unreal Engine version 4.27

Why is there only a .uasset file in the .zip with no corresponding .uexp file? 🤔

Oops! Just fixed now.
Apologies for not seeing this until now, it fell off my radar for awhile.

Is this related to the files I've posted here? If your build of UassetGUI is crashing when opened, I would think you can just re-download the latest release to fix it.

Я открываю его, и он выдает мне ошибку, но я даже не загружаю uasset туда. Я просто открываю его, и он выдает мне ошибку. Помогите мне.

Это связано с файлами, которые я здесь разместил? Если ваша сборка UassetGUI вылетает при открытии, я думаю, вы можете просто повторно загрузить последнюю версию, чтобы исправить это.

No, I didn't download your file, but I just downloaded, installed and used it for 2 days and after 3 days I open it and it says error

You should really make your own issue for whatever problem this is, probably on uassetGUI's github since it seems to be a problem with that.
Is there any reason you're building from source and not just using the release?
You can grab the latest exe here and see if that fixes your issue: https://github.com/atenfyr/UAssetGUI/releases/download/v1.0.3/UAssetGUI.exe
