[🐞]Netlify deployment fails with Bun: `SyntaxError: Unexpected token ':'` during "Edge Functions bundling"

Start with vite.config.ts and reproduce the failure using bun run deploy, focusing on the Netlify Edge Functions bundling and manifest-validation steps shown in the log. Compare the generated output with the reported bundler failure; done means the project builds and deploys successfully without the Unexpected token ':' error.

Which component is affected?

Qwik Runtime

Describe the bug

Bug Description

Hello,

I am trying to deploy my Qwik project to Netlify using the Netlify Edge adapter. When I run the deployment command (bun run deploy), the build fails on Netlify with an internal error during the "Edge Functions bundling" step.

The reported error is a SyntaxError: Unexpected token ':', which seems to originate from the Edge Functions manifest validation process by Netlify's bundler (@netlify/edge-bundler), specifically when using ajv for schema validation.

Reproduction

Steps to reproduce the issue are as follows:

1. Create a Qwik project with the netlify-edge adapter.
2. Use bun as the package manager and script runner.
3. Configure the project for Netlify deployment.
4. Run the deployment command (e.g., npm run build or an equivalent command).
5. The build fails on Netlify during the bundling process.

Expected behavior

The project should build and deploy successfully to Netlify without any errors during the 'Edge Functions bundling' step.

Logs and Screenshots

Here is the full error returned by the Netlify build terminal:

Additional Context

Here is the content of my vite.config.ts file. It's fairly standard, but I'm providing it for context.

/**
 * This is the base config for vite.
 * When building, the adapter config is used which loads this file and extends it.
 */

import pkg from "./package.json";

type PkgDep = Record<string, string>;
const { dependencies = {}, devDependencies = {} } = pkg as any as {
	dependencies: PkgDep;
	devDependencies: PkgDep;
	[key: string]: unknown;
};
errorOnDuplicatesPkgDeps(devDependencies, dependencies);
/**

export default defineConfig(({ command, mode }): UserConfig => {
	return {

			qwikCity(),
			vanillaExtractPlugin({
				identifiers: mode === "production" ? "short" : "debug",

		// This tells Vite which dependencies to pre-build in dev mode.

	};
});

	dependencies: PkgDep,

	let msg = "";
	// Create an array 'duplicateDeps' by filtering devDependencies.

	// include any known qwik packages
	const qwikPkg = Object.keys(dependencies).filter((value) =>

	// any errors for missing "qwik-city-plan"
	// [PLUGIN_ERROR]: Invalid module "@qwik-city-plan" is not a valid package
	msg = `Move qwik packages ${qwikPkg.join(", ")} to devDependencies`;
	if (qwikPkg.length > 0) {
		throw new Error(msg);
	}
	// Format the error message with the duplicates list.
	// The `join` function is used to represent the elements of the 'duplicateDeps' array as a comma-separated string.
	msg = `
    Warning: The dependency "${duplicateDeps.join(", ")}" is listed in both "devDependencies" and "dependencies".
    Please move the duplicated dependencies to "devDependencies" only and remove it from "dependencies"
  `;
	// Throw an error with the constructed message.
	if (duplicateDeps.length > 0) {
		throw new Error(msg);
	}
}

It seems there might be an incompatibility between the output generated by the Qwik build (likely the server functions manifest) and what the Netlify bundler expects.

Thanks for your help.
