Description

Describe the bug

so having this:

  const link = getContactLink(
    () => ({ id: params.id }),
    () => ({
      deferStream: true,
    })
  );

which basically calls createQuery(...).

this function throws an error, therefore link.data is null so i can't render anything
yet, link.error is always null, i can't render the error and i can't render the data (because no data was returned)

if i remove deferStream then the errors gets printed to the console but still, link.error doesn't return anything.

Research direction

Start by reproducing the SolidStart SSR case described around getContactLink, createQuery, and deferStream using the reported tanstack/solid-query 5.60.5 setup. Trace how the thrown error reaches link.data and link.error during SSR, then verify that the error is exposed through link.error while the existing data behavior remains intact.
