Crash when viewing server's apps

[michiels]

I'm trying to visit the apps overview of a service and getting a crash. Here's the output from production.log:

@jvanbaarsen I think another user hit this error too. Just as a :+1:

[jvanbaarsen]

@michiels Was this a server where IC and Dokku runs on the same server?

[michiels]
