Hey there,
I'm working on a project using Next.js 13 along with an app directory and Sanity v3 CMS. So, I tried to set up on-demand revalidation using the Sanity Webhook. The thing is, my API endpoint gives me a success message and the revalidatePath function seems to run as expected. But the page doesn't actually get revalidated.
I skipped the webhook to pinpoint the problem; my current endpoint looks like this.

export async function POST(request: NextRequest) { const path = request.nextUrl.searchParams.get("path") ?? "/"; revalidatePath(path); return NextResponse.json({ message:Successfully revalidated route: ${path}, revalidated: true, now: Date.now(), }); }

The endpoint returns the correct path. I've tried revalidating "my-path", "/my-path" and "/my-path/page".
I tried using cache tag and revalidateTag, but no dice – got the same results.

Testing process:
Deployed to test environment, published changes in Sanity CMS and manually triggered mypage.com/api/revalidate?path=my-path
which returns: {"message":"Successfully revalidated path: my-path","revalidated":true,"now":1691653561596}

App directory structure:
app (app) (myRouteGroup) my-path page.tsx layout.tsx not-found.tsx (myRouteGroupTwo) page.tsx layout.tsx not-found.tsx (studio)

All help would be greatly appreciated.
