It works using latest LTS release of Node. Update Node from 18.2.0 to latest LTS, and try again.

@kddige Tried Node v18.7.1 and Node v20.6.1 but it is still not working and getting the same response.

Am running into a somewhat similar issue where some routes under app/api are swallowing up console.log statements and function returns. Bizarrely, in one of my apps it is only 3 out of six routes.

Hi,

I have a very similar issue:

• If I run npm run dev the GET endpoint works
• If I run npm run build && npm run start the GET endpoint does NOT work
• If I change the endpoint from GET to POST, it always works!

Example code -- the print is done only with run dev:

export async function GET(_req: NextRequest): Promise<NextResponse>
{
    console.log("GET called")
    return NextResponse.json({})
}

• Node version: v21.1.0
• Next version: 14.1.0

Reproducible on my end as well, console logs are being swallowed by the app router api route. Node version: 20.10.0 Next version: 14.2.3

Edit: My api route was "static" because that is the default behavior on the app router side, and as soon as I made it dynamic, the logs started showing up normally like they should. So apparently logs won't show up only if your api route is static.
