Error: Unhandled Exception: End_Of_File

[tomitrescak]

Hi, I keep receiveing following error quite often:

Error: Unhandled exception: End_of_file
    at ChildProcess.<anonymous> (/Users/tomi/.atom/packages/linter-flow/node_modules/atom-linter/node_modules/sb-exec/lib/index.js:41:20)
    at emitTwo (events.js:100:13)
    at ChildProcess.emit (events.js:185:7)
    at maybeClose (internal/child_process.js:850:16)
    at Socket.<anonymous> (internal/child_process.js:323:11)
    at emitOne (events.js:90:13)
    at Socket.emit (events.js:182:7)
    at Pipe._onclose (net.js:477:12)

I have mixed javascript and typescript files. Any idea what could be the problem?

Do you consistently see this? Are you able to share the files you see this on if so?

[nmn]

Funnily, I started getting these errors recently too. But from a linter-eslint.

@Arcanemagus here's a file I'm consistently seeing this on:

// @flow
import chai from 'chai';
const expect = chai.expect;

import {
  authenticate,
  createAgent
} from '../../../fixtures';

describe('Foo, function() {

  let agent, user;

  beforeEach(async function() {
    agent = await createAgent();
    user = await authenticate(agent);
  });

});

Callstack:

It pops up regularly any time I'm typing. I need to disable the package when working in certain files :/

[nmn]

I think this is an issue with the linter package itself. Ive seen this error on and off in both linter-flow and linter-eslint.

[bgeihsgt]

@nmn If that was the case, then why would the problem go away when I disable linter-flow but keep linter-eslint on?

[nmn]

@bgeihsgt I don't know. I'm just reporting what I've experienced personally.

Lately, I can't reproduce the error at all. But if you could open up the console when you see this error and send us the stack trace that would be very helpful.

[bgeihsgt]

@nmn I opened up the console and repro'd the red box but saw nothing on the console. Is the strack trace from the red box not sufficient?

[Arcanemagus]

Unfortunately the only part of that stack trace that means anything is Unhandled exception: End_of_file, which is coming from the stderr output of the command (flow). Why flow is returning that is the question...

@nmn I've yet to see a report on linter-eslint that shows that, are you sure it's not just flow running on the same files and hitting the same thing?

[Arcanemagus]

Possibly related to https://github.com/facebook/flow/issues/1693, it looks like there are a few different issues over there related to this message.

I'm still receiving this error on atom while using linter-flow. On VSCode with Flow Language Support module, it works fine.
