`result` parameter in `combine` function in `useQueries` initially empty array

[dhulme]

Describe the bug

The result parameter in combine function in React useQueries is initially an empty array. This doesn't match the typing that says each item is a UseQueryResult.

Steps to reproduce

Run example and look in the console, it shows an error (see screenshot below).

For an unknown reason, the code works in code sandbox, but not when I run the same code example on my machine or my colleague's machine. Please could you try and reproduce locally copying the 3 files in the example?

For an unknown reason, the code works in code sandbox, but not when I run the same code example on my machine or my colleague's machine.

not sure what's up with the sandbox, but it's somehow using an older version of react-query.

here is a fork with an update to the latest version that shows the issue:

• https://codesandbox.io/p/devbox/practical-turing-8w2szg?file=%2Fpackage.json%3A12%2C46

this seems like a regression from:

• https://github.com/TanStack/query/issues/6369

I need to see if I can fix that issue differently.
