Issue 1 Description

I am following the migration guide to Parse Server 6, and encountered couple of issues.

I have changed my code to use simpler initialisation:

parse-server/6.0.0.md

Line 28 in 76c7a6f

const ParseServer = require('parse-server');

And I get the following error:

const api = new ParseServer({...});
            ^

TypeError: ParseServer is not a constructor

I still have to use the old method of const ParseServer = require('parse-server').ParseServer; to get the proper constructor.

Issue 2 Description

Trying to start the parse server in async way via:

await api.start();

Produces the following error:

  await api.start();
  ^^^^^

SyntaxError: await is only valid in async functions and the top level bodies of modules

I have to use the following workaround to actually produce async context on top level of my index.js:

(async function main () {
  await api.start();
})();

SyntaxError: await is only valid in async functions and the top level bodies of modules

Which Node version are you running? await on top level is unflagged since Node 14.8.0.

@mman I followed the migration guide and the directions worked for me. Your error seems to be related to how you are calling your async method. My updated code is here for reference: https://github.com/netreconlab/parse-hipaa/blob/89ccb02db7970ffd494a1dae907f9a660e117171/parse/index.js#L407-L409. I used the 6.0.0-alpha.21 image for testing my development servers, but it worked on 6.0.0-alpha.17 also.

As far as your first issue, I still used the old way as well...

@dblythy Could you take a look at @mman's issue 1?

@cbaker6 Looks like you are calling async function from top-level without await, and in your async function then await parse.start(). I am calling await parse.start() on the top level and that fails. Node 16.

@mtrezza This is happening for me on Node 16.
