[ionic serve] Error ECONNRESET - Reload and websocket error breaks server

[peterpeterparker]

Short description of the problem:

With the last update of Google Chrome, when I refresh a page, the local server (ionic server) breaks.

According @DeMoorJasper in the parcel project, the problem comes when disconnecting the client websocket from the server, which resulted in ECONNRESET, which was ignored in WS 3.3.2 but now triggers an unmatched error

According @iMediaSolutions downgrading the ws dependency of ionic-app-scripts solve the issue (see ionic forum)

What behavior are you expecting?

It should be possible to refresh or reload an app or page etc.

Steps to reproduce:

1. ionic serve
2. access http://localhost:8100 in Google Chrome (or Opera)
3. click refresh (in the browser)
   => server stops/breaks

Hi! got the same issue from yesterday.
and finaly find solution.
Bug is cause by the latest ionic-app-script pkg using as dependecies ws v.3.3.3 and this version do not working with the latest version of google chrome.

To fix:
remove ./node_modules/ws folder and run $npm install [email protected]

Now we waiting an ionic-app-script update to fix it.
Enjoy

I can confirm the issue is fixxed with [email protected]

[villarres]

this solution works for myApp tabs but does not work with myApp blank and myApp sidemenu.
You can try them to see because npm install [email protected] resoud only for myApp tabs

[mhartington]

Hey there! Can you please install the nightly version of app-scripts to verify that all is fixed.

npm install @ionic/app-scripts@nightly --save-dev

This just pins the version to 3.3.2 for now until we properly update ws.

[mhartington]

3.1.6 is out now, which has the fix. Please upgrade your app-scripts version

[bernardlau92]

3.1.6 solves the issue. Thank you.

[peterpeterparker]

@mhartington thx, the fix works perfectly

[EugeneSnihovsky]

@mhartington It may be useful to update ionic change log (version of ionic-app-script is hardcoded on 3.1.0 there)

[newsof1111]

have you try adding --local to your cmd?
