  • Can you [edit](https://stackoverflow.com/posts/75731340/edit) your question and paste your code as code blocks instead of images. What is the error you're getting? Could you add that to the question as well? – RubenSmn Mar 14 '23 at 09:39

A common issue with the router is that the query param is undefined on the first render. You can use router.isReady or check that the id is not undefined before sending the api call
