Undefined is not an object (evaluating '$.get(roomStore).participants')

[markdomkan]

Describe the bug

I'm creating a global store with $state and i'm exporting it with getter. When i'm using that store in #each, i getting Undefined is not an object (evaluating '$.get(roomStore).participants') error in my console. That error is not happening if I add $effect(() => void roomStore.participants); on script section.

Reproduction

You can check that here:

• download this repo https://github.com/markdomkan/join
• install dependencies (i'm using bun, but can be done with node)
• run it with dev script.
• enter on http://localhost:5173
• click on "create new room"

you should get the error in your console.

The implicated files are:

• src/lib/store/room.svelte.ts
• src/lib/components/Participants.svelte

If you uncomment the line 6 of Participants.svelte, the error should disappear
