Trouble with "export async function"?

[lll000111]

Output

I'll just show errors for one file. There are several. but the location always is an export async function line.

mha@mint-virtual-machine ~/Projects/one.moddable/DEVICE $ mcconfig -d -m -p lin

Code

In module-importer, starting from line 34:

...
// NEXT LINE: #34
export async function createObjects(WriteStorage, {
  moduleName,
  version = '1.0',
  code
}) {
  let clobResult;

  try {
    clobResult = await WriteStorage.storeUTF8Clob(code);
  } catch (err) {
    err.stack += new Error().stack;
    throw err;
  }

  if (clobResult.status === CREATION_STATUS.EXISTS) {
    MessageBus.send('log', `Code CLOB ${clobResult.hash} already exists`);
  }

  const module = {
    type: 'Module',
    name: '@module/' + moduleName.replace(/\.js$/, ''),
    provides: [],
    requires: extractRequires(code),
    version,
    code: clobResult.hash
  };

  try {
    return await WriteStorage.storeVersionedObject(module);
  } catch (err) {
    err.stack += new Error().stack;
    throw err;
  }
}

It indeed looks like this particular syntax causes problems.

Workaround

I removed the export from those functions and do an extra export {theFunction}; at the end of the file. Those errors have stopped showing up.

Instead of

export async function myFunc () {
   ...
}

I now write

async function myFunc () {
   ...
}

export {myFunc};

Thank you for the detailed report. A fix will be available in the coming days.
