Can't access translations in edge api route

[wottpal]

Description

I'm having a simple app/api/route.ts api route like:

import { getTranslations } from 'next-intl/server'

export const runtime = 'edge' // works only, if i comment this out

export async function GET() {
  const t = await getTranslations('Metadata')
  return new Response(t('name'), {
    status: 200,
    headers: { 'Content-Type': 'text/plain' },
  })
}

And this actually throws:

Error: `getTranslations` is not supported in Client Components.

…which is a bit randomly worded in the first place. And if i comment export const runtime = 'edge' out it works seemlessly.

How to use next-intl in an edge runtime? Also, I'm happy to pass the locale manually if that's the problem (which i do have at hand in this case in the edge environment).

Thanks in advance! :)

Expected behaviour

getTranslations should work in edge runtime environments.

Interestingly, the same error occurs when trying to use unstable_setRequestLocale ("[…] not supported in Client Components")

Hmm, that error is quite odd.

I've tried this out in a local example in this repo that uses a Route Handler:

https://github.com/amannn/next-intl/blob/ed4681fa70b8f67a97e1364deaabf58df302d80c/examples/example-app-router-playground/src/app/%5Blocale%5D/api/route.ts#L10-L18

For me this works in the edge environment. I've also tried not providing the locale (await getTranslations('ApiRoute')) and it seems to work regardless. You might want to consider passing the locale to getTranslations in the Route Handler when in doubt (this enables static rendering, if relevant).

If you're still running into an issue that you can trace back to next-intl, please provide a reproduction.
