handleDataRequest not work

[Yiniau]

export handleDataRequest function in app/entry.server.tsx

export function handleDataRequest(
  response: Response,
  { request, params, context }: DataFunctionArgs,
) {
  console.log("request", request);

  const cors_headers = cors(request);
  for (const [k, v] of Object.entries(cors_headers)) {
    response.headers.set(k, v);
  }
  return response;
}

but not see any log in shell

handleDataRequest only works when Remix does a client-side request to a UI route loader or action, which happens when it has the ?_data search param.

If /api_gateway/lemmy is a resource route it will not be used, for resource routes you will have to apply CORS manually.

This is very helpful, thank you! However, is this mentioned in the official documentation?
