How do I troubleshoot NGXS issues in my Angular application?

I'm having trouble with state management in my Angular app using NGXS. What should I do?

First, can you describe the specific issue you're facing with NGXS? Are you getting any error messages?

Yes, I'm getting an error that says 'Cannot read property of undefined' when trying to access the state.

This usually happens when the state is not properly initialized. Make sure your state is defined and initialized correctly in your store.

I checked, and the state is defined. What else could be wrong?

Another common issue is not selecting the state correctly in your component. Ensure you're using the correct selector to access the state.
