SyntaxError: Unexpected end of JSON input

[eyalev]

I installed chromix-too and everything worked for about an hour but now when I run something, e.g:

$ chromix-too focus gmail

I get the following error:

The server give the following output:

Is there a way to fix this?

I'm running on Ubuntu 14.04.

(And thanks for the awesome project!)

Ok, so chromix is now working again, I don't really know what happened.
Closing for now. Thanks.

Hmm.

I've no idea what was going on either. Glad it fixed itself!

[eyalev]

Happened again right now
Seems to be related to the number of tabs open.
When I have more than 122 tabs (123 and above) I get this error.
When I close tabs to get to 122 or below - chromix works great.
Is there a way to fix this?

[smblott-github]

A couple of things...

1. I can't reproduce this. I created 150 tabs and - while it was a bit slow - nothing failed.
2. If it's triggered by more than exactly 122 tabs (or any number), then It seems really quite unlikely, on the face of it, that this is a chromix-too issue. There really are no numbers build into chromix-too.

If you're able to reproduce this reliably then it would be helpful to hear what if anything is appearing on the dev console in Chrome:

• go here: chrome://extensions/
• enable developer mode
• open the background page for chromix-too
• is there anything interesting appearing on the console?

Followed the steps.

WebSocket connection to 'ws://localhost:7442/' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED
tryConnect @ background.js:68
background.js:59 disconnected, retry connection in 5000ms...
background.js:74 connected: ws://localhost:7442/
# All works fine with less tabs
# Time goes by..
# Here I opened more tabs and executed `chromix-too ls`

Don't see something interesting..

I'm running into the same problem, when fetching many cookies from Chrome:

SyntaxError: Unexpected token d in JSON at position 65532
    at JSON.parse (<anonymous>)
    at Socket.<anonymous> (/usr/lib/node_modules/chromix-too/chromix-too.js:32:25)

    at Socket.Readable.push (_stream_readable.js:136:10)
    at Pipe.onread (net.js:560:20)

Only happens when there are 100+ cookies.

It seems there is a limit of 65536 characters somewhere. Where would this limitation most likely be? In the JSON serializer, websocket or Chrome itself?

ping @smblott-github this issue is a blocker for using it, almost all commands hit that bug

Note I have "large urls" caused by the awesome extension "the great suspender" which transforms stale tabs into png's, see https://chrome.google.com/webstore/detail/the-great-suspender/klbibkeccnjlkjkiokjodocebajanakg?hl=en
