Any way to get more details on HasError / ErrorInvalidContent?

I’m fairly new to modding the game, currently I’m trying to mod the sound of an aircraft in 2024 but the package state is showing as:

Mounted | HasError | ErrorInvalidContent

I’m sure I’ve done something wrong but I can’t for the life of me figure out what, and I can’t find any further details on what the error message is/what the invalid content is. Is there any way for me to see more details about the error I’m getting here? Like a tool to view the errors or a log file?

I googled around and read through the documentation but couldn’t find anything relevant for 2020 or 2024. Please let me know if there’s any more details I should include here!

As an aside: Does anyone know if it’s even possible to mod the sound given that everything is streamed in? I can see the sound .PCK file is stored locally but the sound.xml doesn’t appear to be.

For anyone in future looking at this, make sure your JSON is formatted correctly! This just ended up being a trailing comma leftover in the Layout.json that was causing the error (a lesson not to use Notepad to edit JSON haha)
