Error when attempting to stop apps.

[KyleJosling]

I get the following error when attempting to stop an app:

 Stopping ledDemo
 Message recieved from app without active application record /home/pi/matrix-os/apps/ledDemo.matrix/index.js
 Uncaught exception:  TypeError: Cannot convert undefined or null to object

Applications can start but they are not able to stop. I have to reconnect the device using NODE_ENV=rc node index.js every time I want to deploy a new app version

Hi @KyleJosling can you pass me the steps you had done until starting that error? Also, which version of the MOS are you running? Did you try to stop the app from the matrix-cli, matrix dashboard or the mobile app?

Hi @gordinh , thanks for the reply. I'm using the newest version of MOS ( 0.14.0). I'm trying to stop the app from the matrix-cli. To start the MOS i use:

pi@openhab:~/matrix-os$ NODE_ENV=rc node index.js
Environment Selected: rc

Loading...  event
Loading...  service
Not using device data from db, using MATRIX_DEVICE_ID and MATRIX_DEVICE_SECRET instead!

I can run something like

matrix deploy ledDemo
matrix start ledDemo

from the CLI, but as soon as I do

matrix stop ledDemo

It gives me the error above. and the MOS stops.

@KyleJosling thanks for reporting this, it was an issue with some recent changes.

Please update to v0.14.1 and try again, it should be working.
