Hi, could you please specify more about the issue? I'll be happy to take a look at it.

@devjiwonchoi if you have a canonical url in the meta object it comes out different in the actual html rendered. We put in with no / and in the html there is / added.

I cannot reproduce your case; it'd be great if you updated the code sandbox to a valid reproduction.

export default async function Page() {
  return null;
}

export const metadata = {
  alternates: {
    canonical: 'https://acme.com',
  },
};
