I'm currently experiencing an issue with the Tebex v2.0.5 plugin for a game server, specifically related to a JSON deserialization error using the Newtonsoft.Json library. I'm hoping to find some assistance or suggestions on how to resolve this.
Error Description:
I'm encountering an exception during a web request callback in the Tebex plugin. The error message is as follows:
"Web request callback raised an exception in 'Tebex v2.0.5' plugin (Error converting value {null} to type 'System.Int64'. Path 'commands[0].package', line 1, position 391.)"
This suggests an issue with converting a null value to a `System.Int64` type during JSON deserialization.
Attempted Solutions:
- I've checked for any obvious mismatches in the JSON structure and the corresponding C# class properties.
- Ensured all long type properties are correctly mapped and formatted.
Seeking Suggestions:
- Any insights on handling null values in JSON deserialization for non-nullable types like `long` in C#.
- Tips on configuring the JsonConvert settings to avoid such issues.
- Recommendations for error handling practices in similar scenarios.
I am attaching relevant snippets of the code for reference. Any help or guidance would be greatly appreciated as I'm a bit stuck on how to proceed with debugging and resolving this issue.

Hey there, we'd need to see your server logs to assist here. Enable debug mode so that we can see the JSON response received from Tebex, as it looks like the response is in some unexpected state, specifically with a package attached to one of your commands.

To enable debug mode run tebex.debug on, allow the issue to occur again, and share the relevant portion of your server log.

Thank you! It looks like for some reason there's not a package associated with a command or purchase, which is odd:
