A query function can be literally any function that returns a promise. The promise that is returned should either resolve the data or throw an error.
All of the following are valid query function configurations:

Ah, thanks. So basically I should throw Error in mutation - then its is logged as Error, but not uncaught. However in svelte version when throwing error inside mutation fn i see uncaught Error, whereas in react there is no "uncaught". Its bug or something?
