404 Error in Category Menu in Sanity + Next.js

Sorry again, I'm still struggling with a category menu in a Sanity + Next.js project. I've been trying to add a

pages/[slug].js

file to display posts only in a selected category but anything I've tried resulted in errors (most notable one being a cors error – I probably did something wrong there). I've tried to reproduce an error and the simplest version I could come up with is cloning the

vercel/next.js

example and copying the

pages/posts/[slug].js

's contents into the

[slug].js

(and adjusting the import paths). In this case I get a 404 error while the

pages/posts/[slug].js

works properly. Is this example supposed to work or is it that I don't know something really obvious (I'm fairly new to both Sanity and Next)?

can you reproduce in codesandbox or stackblitz?

HI - I'm not a next.js user, but I would imagine that the

pages/[slug]

route is expecting to present data from a single

page

. Is the next app working on its own? Is your query working on its own? If you include links to code or paste in the parts you are working on someone will take a look!

Thank you for replying, I've figured it out by now. …It was a misplaced comma that was causing weird errors 🤦
