Hello Deno team,I'm hoping you can help me with a persistent deployment failure on Deno Deploy. I'm trying to deploy a very simple API middleware server that takes a JSON request, converts it to XML, and forwards it to an external API. The code works perfectly when run locally.However, every deployment attempt fails with ISOLATE_INTERNAL_FAILURE immediately after the "Packaging complete" step in the build logs. I am fairly confident this is a platform-level issue, as I have exhausted all the troubleshooting steps I can think of.My Deno Deploy project name is: salesforce-middlewareCodeHere is the complete code for the project.main.ts// main.ts
import { serve } from "https://deno.land/std@0.217.0/http/server.ts";
import { XMLParser, XMLBuilder } from "npm:fast-xml-parser";

// --- Configuration and Credentials ---
const EMERCHANTPAY_URL = 'https://staging.wpf.emerchantpay.net/en/wpf'; 
const empUsername = Deno.env.get("EMP_USERNAME");
const empPassword = Deno.env.get("EMP_PASSWORD");

// --- Pre-flight Check ---
if (!empUsername || !empPassword) {
  console.error("CRITICAL STARTUP ERROR: EMP_USERNAME or EMP_PASSWORD is not defined.");
  console.error("The server will not start processing requests until these environment variables are set.");
} else {
  console.log(`✅ Middleware server starting...`);

  serve(async (req: Request) => {
    const url = new URL(req.url);
    if (url.pathname !== '/' || req.method !== 'POST') {
      return new Response("Not Found", { status: 404 });
    }

    try {
      const salesforceJson = await req.json();
      const objectForXml = {
        wpf_payment: {
          ...salesforceJson,
          transaction_types: {
            transaction_type: {
              '#text': '', 
              '@_name': 'sale'
            }
          }
        }
      };
      
      const builder = new XMLBuilder({
        format: true,
        ignoreAttributes: false,
      });

      const xmlPayload = builder.build(objectForXml);
      const authHeader = `Basic ${btoa(`${empUsername}:${empPassword}`)}`;

      const empResponse = await fetch(EMERCHANTPAY_URL, {
        method: 'POST',
        headers: {
          'Content-Type': 'application/xml',
          'Authorization': authHeader,
        },
        body: xmlPayload,
      });

      const emerchantPayXmlResponse = await empResponse.text();

      if (!empResponse.ok) {
        throw new Error(`eMerchantPay returned status ${empResponse.status}`);
      }
      
      const parser = new XMLParser({ignoreAttributes: false});
      const jsonForSalesforce = parser.parse(emerchantPayXmlResponse);

      return new Response(JSON.stringify(jsonForSalesforce), {
        headers: { 'Content-Type': 'application/json' },
        status: 200,
      });

    } catch (error) {
      const errorMessage = error instanceof Error ? error.message : "Unknown error";
      console.error("An error occurred in the middleware:", errorMessage);
      return new Response(
        JSON.stringify({
          status: "error",
          message: "Middleware processing failed.",
          details: errorMessage,
        }),
        {
          headers: { 'Content-Type': 'application/json' },
          status: 500,
        }
      );
    }

Packaging complete
The deployment failed: ISOLATE_INTERNAL_FAILURE
Troubleshooting Steps Already TakenI have tried all of the following, and each one results in the same ISOLATE_INTERNAL_FAILURE:Removed Forbidden APIs: My code does not use Deno.exit() or other system-level APIs forbidden in Deno Deploy.Removed dotenv: I removed the dotenv dependency to simplify the dependency graph, relying only on environment variables injected by the platform.Aligned std versions: I tried aligning all deno.land/std imports to the same latest version (0.224.0).Used Older std version: I reverted the std library version to a known-stable older version (0.217.0), which is reflected in the code above.Removed deno.jsonc: I tried deploying without a deno.jsonc file entirely to rule out a configuration issue.Could you please take a look or let me know if there's a known platform issue that might be causing this? Any help would be greatly appreciated!
