Error in Next js 13 App routes

[Dru1DD]

When I generate Pdf on api/route in Next Js 13 I got an error that isn't suitable as server component.

 ⨯ Class extends value undefined is not a constructor or null

This might be caused by a React Class Component being rendered in a Server Component, React Class Components only works in Client Components.

It seems, that package didn't compared for app routes

Try to add "use client" in the beginning of the file.

Yeah, you're right. But I have told about api/route. I generate pdf on server side with package react-pdf/renderer and method renderToStream - works only on server ( express js ) or api/route. And there it doesn't work.
