Try changing line 17 to {isShowing.value && <ClientOnlyComponent />}

Yes, that will work for sure, but I can already work around the issue. The point is that totally valid code causes the runtime to throw an error and quit.

The Stackblitz project is the simplest form I could find that would reproduce the problem. It's not representative of the code I'm actually trying to write (something similar to the Portals example in the docs)

The bit that's interesting is the code was initially using useComputed:

const Comp = useComputed$(() =>
  isShowing.value ? ClientOnlyComponent : undefined
)
return(
   ....
   {Comp3.value && <Comp3.value />}
   ....
)

Which also didn't work, but this did

const Comp = isShowing.value ? ClientOnlyComponent : undefined;
...
{Comp && <Comp />}

which is why I tried contriving what's in the Stackblitz code

const Comp = isShowing.value ? { value: ClientOnlyComponent } : {}
...
{Comp.value && <Comp.value />}

What's the difference between 2 & 3? Why does having Comp stored in an object propety make a difference?

qwik only serializes context that is used during SSR. Are you using useLocation anywhere during SSR? If not, add it somewhere.

This is a feature to prevent sending useless context data to the client.

If this was the problem, how should the error message have been changed to make this clear to you?
