Heroku: Error: connect ECONNREFUSED 127.0.0.1:9222 about nickjs HOT 17 OPEN

I'll update the readme if you can confirm that it's working with an older version :)

from nickjs.

@wbelk possibly, it is similar to this?
Cannot connect to the target: connect ECONNREFUSED 127.0.0.1:9222

Well...when I deploy to production environment I am getting the same error.
There are no google-chrome instances running and so I have no idea what to do next.

node: v8.12.0
npm: 6.4.1
google-chrome: 69.0.3497.100

from nickjs.

I figure this out, but, this is really weird for me.

Before, start taking about how I figure this out, nodejs and pm2 are installed globally.
The reason why I have pm2 is that I used to have nodejs based API with nickjs.

■Steps to figure this out.

① Execute my old nodejs based API with 1 process.
② Create HTTP request to API from 1.
Note: nickjs should be used by the API
③The process from ① should be kept all the time in order to run nickjs, otherwise, I get the same error.

I do not know why I have to keep running my old API.
Also, I tried restaill nodejs, pm2 and Google Chrome.
But, this dose not work.

Of course, when I get this error, chrome is not up and running.

If you have any idea, please let me know.

If I understand correctly, your NickJS script, for some reason, cannot start the chrome subprocess in your environment. But in older Heroku environments, it does work like it should.

Can you please add debug: true to your NickJS' constructor options? And report back with what it shows

In containerized/dockerized environments, starting chrome can be a pain. A simple google search shows many people having difficulties. For example chrome must be started with --no-sandbox (which NickJS does), the container should have a big shm size, etc... Maybe the newer Heroku has stricter container settings?

I have the same error on Ubuntu 16.04, I tried node v8 and v11.6, chromium, chrome 70, 71,72,73(unstable).. I specified export CHROME_PATH="/usr/bin/google-chrome"; , also tried /opt/google/chrome/...

Edit: I solved it by starting chrome 71 like this: google-chrome --remote-debugging-port=9222 --no-first-run, --no-default-browser-check, and --user-data-dir

from nickjs.

@elhenro are you starting chrome by hand alongside NickJS?

from nickjs.

affirmative, the only way for me right now is to quit chrome completely and then start it with those options

from nickjs.

Can you please add debug: true to your NickJS' constructor options? And report back with what it shows? (do not start chrome by hand, I just want to see what happens on NickJS' side when it fails)

from nickjs.

Sorry for late reply.
Currently, my app is running on production and I can not stop it right now.
So, when I have a chance for it, I will add debug: ture to see what happen to Nickjs.

I guess you have to give the permission to Windows.

Ubuntu 16.04.5 LTS

I got following errors.

I am still getting the same error and so I have to do the follow the steps that I mentioned.
By the way, I am getting error on Ubuntu machine and I do not know what to do next.
If you can help me out, I will give you more details.

from nickjs.

It might be because it's a too recent version of Chrome. Can you try with Chrome 65? I know it's old but it might do the trick

from nickjs.

@paps when I have a chance for that, I will switch to chrome 65.
Can it downloaded from here?

from nickjs.

Then, I guess you had better to write what chrome version supported, otherwise, people get stacked like me.
