<p>I'm using the Prismic API to get some data that I want to display in a Nuxt3 template. </p><p> Everything works fine, I just want to show a 404 page when there is no data, not a 500 error. I added a check to see if the data is empty: </p> <pre class="brush:html;toolbar:false;"><script setup> const route = useRoute() const name = route.params.werke; const { client } = usePrismic() const { data: werk } = await useAsyncData('werk', () => client.getByUID("werk", name)) if (!werk.uid) { throw createError({ statusCode: 404, statusMessage: 'Page Not Found' }) } </script> </pre> <p>The problem is that in the <code>if (!werk.uid)</code> section werk.uid is always empty. So I always get a 404 error. In my template, werk.uid is not empty, so I think there is a problem, the if statement cannot access the const variable using useAsyncData? </p> <p>Any ideas? The official documentation recommended me in a similar way: https://v3.nuxtjs.org/getting-started/error-handling/#example-1</p>
