Compiling typescript resolver with esBuild throws `Unexpected token 'export'` on import '@aws-appsync/utils/dynamodb';

[mattiLeBlanc]

Hi,

As directed in the docs (https://docs.aws.amazon.com/appsync/latest/devguide/resolver-reference-overview-js.html#migrating-resolvers) I am using the Dynamodb module:

import * as ddb from '@aws-appsync/utils/dynamodb';

but when I build my TS to JS I am getting an error from my esbuild:

export * from './lib/dynamodb-helpers';
^^^^^^

SyntaxError: Unexpected token 'export'

    at wrapSafe (node:internal/modules/cjs/loader:1178:20)

    at Object.require.extensions.<computed> [as .js] (/Users/mattijs/www/respark/apollo/apollo-client-api/node_modules/ts-node/src/index.ts:1608:43)

I am building my ts as follows:

const result = esbuild.buildSync({
    stdin: {
      contents: file,
      loader: 'ts',
    },
    external: ['@aws-appsync/utils'],
    bundle: true,
    write: false,
    platform: 'node',
    target: 'esnext',
    format: 'esm',
    sourcemap: 'inline',
    sourcesContent: false,
  });

I tried adding the '@aws-appsync/utils/dynamodb' to externals but to no avail.

How do I resolve this issue?
