Suggestion for improving type inference

[Gruzchick]

Hi! Before all, I am want to say a great job )!

I have a similar code:

`const fetchData = async (
key: string,
place: PlaceType,
) => {
/* some code */
};

const place : PlaceType | null = useSelector(/* some code*/) // place in some cases may be "null" !

const info = useQuery({
queryKey: place && ['currentWeather-${place.id}'],
variables: [place],
queryFn: fetchData
});`

And I get a type error because of the typescript infer that a null value can be passed to the function. But essentially, in the "queryKey" property, I made type guard. I'm not sure if this can be implemented, but it would be cool.

Although perhaps I did not understand how to use this right way )

queryKey cant be null or false
if you want to disable the query until you have place,
you can use something like:

const info = useQuery({
  queryKey: ['currentWeather', place?.id],
  queryFn: () => {
    // do something with place
  },
  config: { enabled: !!place }
});
