useCombobox with multiple item types

[Rangoons]

Hello!
We are trying to use one combobox to render two different types of data that are returned from two different search indices. Is this possible with useCombobox et al?

I've gotten together to return the data from load in useAsyncList as [...dataSet1, ...dataSet2] and it works fine if I just render the stringified item. ie:

 {(item) => (
          <Item key={item.name}>
            {JSON.stringify(item)}
          </Item>
        )}

however, once I start to actually determine the type of item it is & render that way, I keep running into the error Error: No key found for item it seems to only happen if mixed items are rendered. Is it not possible to render multiple data sets in one list or am I going about this incorrectly

Mind sharing a codesandbox/code snippet? Does each item in your data list from useAsyncList have a name?

[Rangoons]

Yes, they both have a name property. Logging the items also did not show any items with a key missing/undefined

I can't get the sandbox to error so maybe its just back to the drawing board for me but here is a rough implementation of what I'm doing

Update - I believe it was just a case of some of the async object's having the property of name but the value being undefined. I appreciate the help 🤝
