I have a nextjs app and a route that serve files. The app builts perfectly with no error, it deployed perfectly, everything works perfectly except that route.
Requesting to that route throws DYNAMIC_SERVER_ERROR no matter which file.

This is the error:

app-1      | ⨯ Error: Dynamic server usage: Route is configured with methods that cannot be statically generated.
app-1      |     at processTicksAndRejections (null) {
app-1      |   description: 'Route is configured with methods that cannot be statically generated.',
app-1      |   digest: 'DYNAMIC_SERVER_USAGE'
app-1      | }
