Thanks for the tutorial I just tried this out in my CDK Typescript project and it deploys fine, but when I try calling the endpoint Appsync throws "Unable to transform the template" import esbuild from 'esbuild'; export function bundleResolver(entryPoint: string): string { const result = esbuild.buildSync({ entryPoints: [entryPoint], bundle: true, write: false, platform: 'node', target: 'esnext', format: 'esm', sourcemap: 'inline', sourcesContent: false, }); if (result?.outputFiles && result?.outputFiles?.length > 0 && result?.outputFiles[0]?.text) { return result.outputFiles[0].text; } else { throw new Error('Bundling failed: No output files generated'); } }
