How to enable the error

1. clone and run the repo and everything works fine...
2. Go to src/content/post-one.md and uncomment the following:

<!-- <script context='module'>
  import Clock from '$lib/Clock.svelte'
  metadata.icon = Clock;
</script> -->

then run again, or keep running...you should then get this error:

I don't know why or what's going on, but thank you in advance for taking a look XD
