Having difficulty integrating Supabase Auth in edge function

[hesham-ayad]

I set up the client like how multiple examples showed, and it worked and was able to getUser, and then suddenly it doesn't anymore and gives me this error:

[Info] AuthRetryableFetchError: error sending request for url (http://127.0.0.1:54321/auth/v1/user)
    at _handleRequest (file:///tmp/sb-compile-edge-runtime/node_modules/localhost/@supabase/auth-js/2.65.0/dist/main/lib/fetch.js:111:15)

  __isAuthError: true,
  name: "AuthRetryableFetchError",
  status: 0,
  code: undefined
}

And this is the edge function code:

import "jsr:@supabase/functions-js/edge-runtime.d.ts";
import { corsHeaders } from "../_shared/cors.ts";
import { createClient } from "jsr:@supabase/supabase-js@2";

Deno.serve(async (req) => {
  if (req.method === "OPTIONS") {
    return new Response("ok", { headers: corsHeaders });
  }

  try {
    const supabase = createClient(
      // Supabase API URL - env var exported by default.
      Deno.env.get("API_URL") ?? "",
      // Supabase API ANON KEY - env var exported by default.
      Deno.env.get("ANON_KEY") ?? "",
      // Create client with Auth context of the user that called the function.
      // This way your row-level-security (RLS) policies are applied.
      {
        global: {
          headers: { Authorization: req.headers.get("Authorization")! },
        },
      },
    );

    const { data, error } = await supabase.auth.getUser();
    console.log(error);
    if (error) {
      // console.log("Error fetching user:", error.message);
      throw new Error(error.message);
    }

    return new Response(JSON.stringify(data), {
      headers: { ...corsHeaders, "Content-Type": "application/json" },
      status: 200,
    });
  } catch (error) {
    return new Response(JSON.stringify({ error: error.message }), {
      headers: { ...corsHeaders, "Content-Type": "application/json" },
      status: 400,
    });
  }
});

I am not sure what is causing this, it's driving me up the wall.

This is running locally.
