Issue Custom Map - "Object reference not set to an instance of an object"

[AKALukeFTW]

Hi friends!

I've tried making a custom map mod in Tiled. I've read the Stardew wiki and watched some tutorials, but still have an issue with the map not loading into my game with SMAPI.

I've downloaded SMAPI (I can load other mods into the game just fine, just to check that it's working - but I'm not running any atm).
I've downloaded and unzipped the content patcher into the mod file for stardew.

I've included the SMAPI error below - if anyone has run into the same issue and might know a solution :)

Thank you!

Fixed the issue - needed to create Type in tile custom properties for the 'Back' layer.
- added grass sound

Hello! I'm having the exact same issue and I've gone through my tile properties and made sure they're all set, yet it still won't load? Any help appreciated
