(aws-lambda-nodejs): NodejsFunction with WebAssembly support

[owenbirdsall]

I'm trying to use a library (lucid-cardano) in my NodejsFunction. Lucid uses wasm, and when calling Lucid I get an error about empty references for its wasm modules.

I've tried adding NODE_OPTIONS: "--experimental-wasm-modules" to my environment variables, but sadly this did not fix the issue. I was wondering if there is anything else I need to do, or if anyone has managed to get wasm running in their NodejsFunctions?

Here's my CDK NodejsFunction constructor:

new NodejsFunction(scope, "lucidFunc", {
  bundling: {
    minify: true,
    preCompilation: true,
    esbuildArgs: {
      "--resolve-extensions": ".js",
    },
    tsconfig: path.join(__dirname, `./lambda/tsconfig.json`),
    format: OutputFormat.ESM,
    target:'esnext',
    mainFields: ['module', 'main'],
    banner: "import { createRequire } from 'module';const require = createRequire(import.meta.url);"
  },
  handler: 'handler',
  entry: path.join(__dirname, `./lambda/${name}.ts`),
  environment: {
    NODE_OPTIONS: "--experimental-wasm-modules"
  }
});
