App Directory: Uncaught Error: DYNAMIC_SERVER_USAGE with NextJS 13.5.4, BlitzJS 2.0.0-beta.34

[tordans]

What is the problem?

I created a fresh blitz app, added a project model with some user relation and migrated it to the app directory.

The app now shows the error message

Unhandled Runtime Error
Error: DYNAMIC_SERVER_USAGE

I also faced this issue while doing server-side rendering, I noticed that when I'm able to access my page by going from "/" to "/dashboard" BUT can not access "/dashboard" directly. In my component, I want to use useQuery to render my component. (dateString props is passed by dynamic page rendering)

// Dashboard.jsx
const Calendar = ({ dateString }: { dateString?: string | undefined }) => {
  let currentDate: Date = new Date();
  if (dateString) {
    currentDate = convertDateStringToDate(dateString);
  }
  const [scheduledClasses] = useQuery(getClasses, {
    dateString,
  });
  
  // ...other code
 return ( // .... )
}

The error won't appear if I removed useQuery but it is not what I want. I temporarily fixed this by forcing the code to use client-side rendering with this trick:

// DashboardLayout.jsx
const [render, setRender] = useState(false);
  useEffect(() => {
    setRender(true);
  }, []);
// ...
<AppShell.Main>{render && children}</AppShell.Main>

by forcing the code to use client-side rendering

I have 'use client' in every file in the app directory + blitz-client. This seems to be needed, since BlitzProvider is a client component (I just opened blitz-js/blitzjs.com#847 to clarify this in the docs).

My understanding is, that the use client directive makes it a client component.

I temporarily fixed this by forcing the code to use client-side rendering with this trick…

I tried your setRender workaround in FixMyBerlin/blitz-test@e31eeed but that has no effect on the error:

And adding it to the layout as well causes new hydration errors.

It looks like this error came from a library that we used 'osm-auth'. Once I remove it, the error is gone. I will close this here and referenced it at osmlab/osm-auth#124.

@siddhsuresh FYI I reopened this ticket. We managed to somehow get rid of the error in our main flow which is why I thought it was related to the library I mentioned but that was wrong and I could have know because the demo app that this bug report is based on (https://github.com/FixMyBerlin/blitz-test) shows the error without without any special dependencies.

Thanks for the update @tordans I will take a look in some time.

Ran into this issue while migrating a Blitz app from pages router to app router. Managed to isolate the issue to useQuery.
@NoahJinnn's fix of forcing the page to render client side with the useEffect() hook worked for me.
