Type 'null' is not assignable to type 'PropertyKey'.

Hi,
I got to the wall with this, as I see I should make a whole new interface just for the store entity because it can't be a null type as the entity interface in the project has. In the project, due the validation object is created with all null values then is populated with data. In the case of ID property, it is also null when it is created until it is saved through API and after API returns ID it is populated with type number and should be saved to the store/state.

The entity will never be sent to the store with a null value, but still, it is needed. Do you have any suggestions that are not turning of strict type from the project?

Thank you.

The idKey can't be null, try to cast it as any or something.

You can also override it: withEntities<ICar & { id: number }>

Thank you, but I didn't have success with that, on other places errors has appeared, I will try to make example with stackblitz.

For now I made modification on the project. I removed nullable type from entity ID and replaced null with zero in entity class.

You can't have neither null nor multiple zeroes as your entity keys.

Entities collection works pretty much like database table with primary key - it has to be unique and not null in order to keep integrity.

If your entity ID prop is nullable by design then you have to add another property that behaves like PK to your model (like random number or guid or props combination).
