queryClient.fetchQuery doesn't deduplicate requests

[vitaliidm]

Hey community!

I have encountered issue using queryClient.fetchQuery.

I have a test function

      return queryClient.fetchQuery({
        queryKey: [myKey],
        queryFn: async () => fetchData(myKey),
        staleTime: 60 * 1000,
      });

It called from 2 places in my react app, when myKey is changed from input.
I would expect only one request to be made, since myKey is the same in both invocations of queryClient.fetchQuery and I defined staleTime. But, instead I can see 2 separate requests, with the same myKey. Moreover, when I update myKey to old value, it doesn't returned form cache, instead I see another 2 requests.
Can anyone advice why it happens?

My version 4.29.12
Thanks
