Error when using warn within an async function

[alexjfno1]

I have a dangerfile.js which contains:

import { schedule, warn } from "danger";

const asyncFunction = async () { ... };

schedule(async () => {
  await asyncFunction();
  message('You havent formated the code using prettier. Please run npm run format before merging the PR');
});

When I run it though I get the error:

{
  fails: [
    {
      message: "Danger failed to run `dangerfile.js`."
    }
  ],
  warnings: [],
  markdowns: ["## Error Error

Any idea's as to why it's failing?

[orta]

Yes - it's some of the sandboxing I've been trying to clean up with #378 and #373

It's on my TODO, but generally speaking the code generated by using async functions #373 triggers the sandbox in vm2 to fail. I'd rather remove the sandbox completely for the moment.

[orta]

If you can, try move that async code into a plugin and it'll be fine today

@orta Any idea when it's likely to be fixed?

[orta]

Nope, I work on DangerJS in my spare time, so it's hard to offer any schedule - there's a PR #378, but it's still failing

[orta]

Try see if alpha 20 fixes this 👍

[alexjfno1]

@orta Great that worked!

I'm not sure if this is related but now when I run it on CircleCI I get Error: Cannot find module 'color-convert'

[alexjfno1]

It seems Error: Cannot find module 'color-convert' was a random failure. Everything seems to be working now.
