QuickJS-NG: Cannot call method on Object returned by evalCode

[p-bakker]

When using the QuickJS-NG variant, the return value is always an Object ({})

When using the regular quickjs variant, you get back the actual value returned by .evalCode

import { getQuickJS } from 'quickjs-emscripten';
import { newQuickJSWASMModuleFromVariant } from 'quickjs-emscripten-core';
import qjsNgSync from '@jitl/quickjs-ng-wasmfile-release-sync';
import qjsSync from '@jitl/quickjs-wasmfile-release-sync';

// Passes
describe('Test getQuickJS', () => {
  it('basic execute of function', async () => {
    const QuickJS = await getQuickJS();
    const vm = QuickJS.newContext();

    const result = vm.evalCode(`"Hello!"`);

    if (result.error) {
      console.log("Execution failed:", vm.dump(result.error));
      result.error.dispose();
    } else {
      const retVal = vm.dump(result.value);
      console.log("Success:", retVal);

      expect(retVal).to.be.eqls('Hello!');
      result.value.dispose();
    }

    vm.dispose();
  })
});

// Fails
describe('Test qjsNgSync Variant', () => {
  it('basic execute of function', async () => {
    const QuickJS = await newQuickJSWASMModuleFromVariant(qjsNgSync);
    const vm = QuickJS.newContext();

    const result = vm.evalCode(`"Hello!"`);

    if (result.error) {
      console.log("Execution failed:", vm.dump(result.error));
      result.error.dispose();
    } else {
      const retVal = vm.dump(result.value);
      console.log("Success:", retVal);

      expect(retVal).to.be.eqls('Hello!');
      result.value.dispose();
    }

    vm.dispose();
  })
});

// Passes
describe('Test qjsSync Variant', () => {
  it('basic execute of function', async () => {
    const QuickJS = await newQuickJSWASMModuleFromVariant(qjsSync);
    const vm = QuickJS.newContext();

    const result = vm.evalCode(`"Hello!"`);

    if (result.error) {
      console.log("Execution failed:", vm.dump(result.error));
      result.error.dispose();
    } else {
      const retVal = vm.dump(result.value);
      console.log("Success:", retVal);

      expect(retVal).to.be.eqls('Hello!');
      result.value.dispose();
    }

    vm.dispose();
  })
});

@justjake Any thoughts about this one? Tried to see if I could figure it out, but no dice so far...
