Steps to reproduce

$ npm i -g ndb

$ ndb

events.js:167
      throw er; // Unhandled 'error' event
      ^

Error: read ECONNRESET
    at Pipe.onread (net.js:660:25)

Tell us about your environment:

• ndb version: 1.0.3 (tried 10.0, 1.0.1, and 1.0.2)
• Platform / OS version: Debian 9 testing
• Node.js version: 10.7 (tried 10.6 and 10.4.1)

What is the expected result?

ndb to start

What happens instead?

ECONNRESET error

Thanks for this project. Looking forward to try it out!

Same exact issue here on Arch Linux (Linux 4.17.8-1-ARCH x86_64 GNU/Linux).

I tried Node 10.0.7 and 9.11.2 as well as ndb 1.0.0, 1.0.1, 1.0.2, and 1.0.3.

Ndb uses puppeteer. Most likely this issue is related to pptr issue: puppeteer/puppeteer#290. Could you please try to install all required dependencies and try to launch ndb again?

@ak239 I checked the troubleshooting link you provided and figured out that this seems to be a sandboxing issue with Puppeteer.

Details

Modifying the Puppeteer launch arguments here:

ndb/ndb.js

Lines 35 to 38 in 97d893c

	args: [
	'--app=data:text/html,<style>html{background:#242424;}</style>',
	'--enable-features=NetworkService'
	]

To include --no-sandbox fixed the issue for me:

diff --git a/ndb.js b/ndb.js
index 13fa599..6947312 100755
--- a/ndb.js
+++ b/ndb.js
@@ -34,7 +34,8 @@ updateNotifier({pkg: require('./package.json')}).notify();
     userDataDir: await setupUserDataDir(configDir),
     args: [
       '--app=data:text/html,<style>html{background:#242424;}</style>',
-      '--enable-features=NetworkService'
+      '--enable-features=NetworkService',
+      '--no-sandbox',
     ]
   });

Enabling kernel.unprivileged_userns_clone fixed this for me (via puppeteer/puppeteer#290 (comment)):

sudo sysctl -w kernel.unprivileged_userns_clone=1

Thanks a lot! I created PR that added --no-sandbox flag by default. Sandboxing is not as useful as it is inside Chromium in our environment so we can switch it off for now.

fix is available in 1.0.4 and already published to npm 😄

@ak239 thanks, it is working now

Having the same issue in a docker environment.

node: 10.7.0
ndb: 1.0.6

This is the output:

ndb nodemon -L -r ts-node/register 'src/index.ts'

Is there any possibile solution?

Thank you 😄
