Fix TypeError: Cannot read properties of undefined (reading 'id') bug

[Alwinator]

I have encountered the situation that itemMetadata is undefined. My project crashed with the following exception. However, my tiny fix solves the problem. Unfortunately, I was not able to reproduce the bug outside of my project. However,
it would be great if you could merge my bug fix.
