Two JSON-LD tags #8802
Description
Describe the bug
Sveltekit generates two JSON-LD tags when configured with a domain in a production environment, here's a comparison between the domain and non-domain versions: http://45.56.85.226:3000/ and https://jsonld.shuaixr.xyz/
When JavaScript is turned off in the browser, one of the JSON-LD tags disappears, so I didn't pay too much attention to it initially. However, recently I found that there were also two in Googlebot's crawled pages.
Also, I wrote a Svelte component like this for easy use of JSON-LD:
<script lang="ts">
export let json_ld: unknown;
</script>
<svelte:head
>{@html `
<script type="application/ld+json">
${JSON.stringify(json_ld)}
</script>`}
</svelte:head>
I am a beginner, this error may also be caused by my non-standard svelte component. If so, please inform me of the correct way.
I created a repository to reproduce the bug where there is all the code:https://github.com/shuaixr/jsonld_svelte
I created a website deployment of this repository:
https://jsonld.shuaixr.xyz
Reproduction
1.clone https://github.com/shuaixr/jsonld_svelte
2.npm run build
3.export PROTOCOL_HEADER=x-forwarded-proto && export HOST_HEADER=x-forwarded-host
3.node build/index.js
