pm2 list: cannot read string of undefined

[MichielDeMey]

Possibly related to #1029 and #1009

Ubuntu 14.04 LTS (Server) inside Vagrant
PM2 v0.12.9
io.js v1.6.2

I simply saved my processes using
pm2 save

Then generated a startup script using
sudo pm2 startup -u vagrant

Then rebooted the server to see if it worked.

Here's the callstack I get when trying to list PM2 processes using pm2 list:

> pm2 list

/usr/lib/node_modules/pm2/node_modules/cli-table/lib/index.js:182
      var contents = item.toString().split("\n").reduce(function (memo, l) {
                         ^
TypeError: Cannot read property 'toString' of undefined

    at Parser.<anonymous> (/usr/lib/node_modules/pm2/node_modules/pm2-axon/lib/sockets/req.js:67:8)

On a side-note, I am able to check the processes using pm2 info and pm2 monit, so I assume this is most likely just a visual bug.

Executing pm2 update fixes the error message.

It shouldn't happen with pm2 v0.12.9.
Maybe you had an older version of pm2 running in memory ?
Did pm2 update fixed it permanently or does it happen again if you reboot the server ?

[MichielDeMey]

It happens again on reboot,
I have to execute pm2 update on every restart.

[jshkurti]

Can you npm i -g git://github.com/Unitech/PM2#development and try again please ? :)

[MichielDeMey]

That worked!

Both while PM2 is running and using a clean install.

Waiting for this to reach stable. :)
