500 Server Error when accessing dashboards

Third party integrations HADashboard
1

I recently went through a process of moving HASS and appdaemon/hadashboard from a Pi to a PC. In the process, I upgraded all of the components to the latest versions. It took some time but I got almost everything working. However, even though my automation with appdaemon is working again, I cen’t get any dashboards to work. They all return a “500 Server Error”. If I navigate to the http://hass:5050 page, I get the list of dashboards. However, If I select any of them, I get the 500 error.

I created a hello world dashboard I called test to use to troubleshoot:

title: Hello Panel
widget_dimensions: [120, 120]
widget_margins: [5, 5]
columns: 8

label:
    widget_type: label
    text: Hello World

layout:
    - label(2x2)

It gets the 500 error like the others I brought over from the pi.

When I get the error, there are no new entries in the appdaemon log, the appdaemon error log, or the home assistant log.

I reviewed the hadashboard topics that referenced “500 Server Error” but most of them were from over a year ago and the solutions included waiting for the new version of appdaemon that Andrew was working on, to checking persmissions on files (which I have). I, of course, have the latest version (On the old Pi, I made homeassistant (user and group) the owner of all of the files and I have done that on the new, PC-based system.

Here is an appdaemon log excerpt from a restart:

2019-04-24 12:56:11.548847 INFO AppDaemon Version 3.0.2 starting

I dug into the config_dir warning but can’t figure out what’s wrong. The /home directory is owned by root:root on both the old and new systems and the permissions are 755 on both systems. Below that, the homeassistant and home assistant/.appdaemon directories have the same ownership and permissions.

Are there other places to look to get some hints on what is wrong?

Please post your appdaemon.yaml file so we can have a look. If you haven´t already, add all the logging options to the appdaemon.yaml file to see if you get any more info in the log files:

log:
  accessfile: /home/appdaemon/logs/access.log
  errorfile: /home/appdaemon/logs/error.log
  logfile: /home/appdaemon/logs/appdaemon.log
  diagfile: /home/appdaemon/logs/diag.log

Adjust the paths to where you want the log files.

I had not looked at the access.log file which was configured in my appdaemon.yaml file. It held the clue:

Somehow, I managed to get some files in the compiled directory set up with root:root ownership. After fixing that, the problem disappeared. Thanks for the help.
