Custom App not starting automatically after installation/reboot [MTCAP-L4E1]

Hi,

We have a node application that runs on multiple MTCAP-LEU1 (firmware v1.7.4) as a custom app. But now we’re having problems when installing it on a MTCAP-L4E1 (firmware v5.0.1-AEP) using deviceHQ.

I can see that the app files were downloaded in /var/config/app/app-name but the application is not running automatically after restarting the gateway. It works as expected on MTCAP-LEU1 (v1.7.4) and we didn’t change the code.

I can run the app manually with the following commands:

./Start start

sudo ./Start start

sudo app-manager --command start --appid <APPID>

Output of sudo app-manager --command status:

{
	"Apps" : 
	[
		{
			"AppDescription" : "...",
			"AppId" : "<APPID>",
			"AppInfo" : "Installed by -",
			"AppName" : "app-name",
			"AppType" : "CUSTOM",
			"AppVersion" : "8.3",
			"AppVersionNotes" : "...",
			"Enabled" : true,
			"status" : null
		}
	]
}

Output of sudo app-manager --command list-installed:

{
   "Apps" : []
}

Permissions of the custom app files:

-rwxrwxrwx 1 root root

Permissions of the config file:

-rw-r--r-- 1 root root

And I can see our application in the list of custom apps in the gateway UI (custom apps are enabled).

Any ideas on how to solve this problem?

Thanks,

Rafael
