Solved issue with auth code rewrite using useQuery() + After that error with multiple requests became which doesn't lead to server crash. But the issue seems very disturbing. |

This is reproduced by simply adding asynchronous processing to the handler. import { createServer } from "ultra/server.ts";
const server = await createServer({
importMapPath: import.meta.resolve("./importMap.json"),
browserEntrypoint: import.meta.resolve("./client.tsx"),
});
function wait(ms: number): Promise<void> {
return new Promise<void>((resolve) => {
setTimeout(() => resolve(), ms);
});
}
function App() {
return <html></html>;
}
server.get("*", async () => {
await wait(200);
const result = await server.render(<App />);
return new Response(result, {
headers: {
"content-type": "text/html; charset=utf-8",
},
});
});
Deno.serve(server.fetch);So, this would also occur in a throw promise, using useQuery. There may be a fatal error in |

I have
awaitfor request inserver.get('*', async (context) => {. atserver.tsx.(I need to obtain Supabase session before SSR rendering start to do SSR routing correctly based on authenticated Supabase user permissions).
If I press
[F5]key several times (< 7) in browser then server breaks with errorCannot enqueue chunk when underlying stream is not readable. Readable stream is unavailable. How to fix?!See
