HADashboard server error 500

jenslj · September 24, 2017, 3:40pm

Hi!

Trying to install HADashboard to see what all the fuss is about. But I run into an issue when AppDaemon is started. I was getting no connection at all from my browser but after doing some searching I scaled back on the SSL-certificates and other extras just to see what’s going on. Now I get error 500 when connecting and some logs from the terminal.

Let’s dive in!

So I followed this guide to install HADashboard and AppDAemon. When I start AppDaemon I get:

pi@raspberrypi:~ $ appdaemon -c /home/homeassistant/conf

2017-09-24 17:27:50.498448 INFO Connected to Home Assistant 0.53.0

Looks good right?

If I load http://my.host:5050 I get the 500 error and the following from the terminal:

Traceback (most recent call last):
File “/usr/local/lib/python3.4/dist-packages/aiohttp/web_protocol.py”, line 422, in start
resp = yield from self._request_handler(request)

[middleware for middleware in app.middlewares
AssertionError: Handler <function secure..wrapper at 0x756c6738> should return response instance, got <class ‘dict’> [middlewares ]

So, what’s going on here? What did I miss?

ReneTode · September 24, 2017, 6:55pm

do you have a dashboard made?
how does it look? and where did you put it?

aimc · September 25, 2017, 1:37am

Is that the entire error? None of that is in AppDaemon code so it’s hard to know what is going on …

jenslj · September 25, 2017, 6:16am

Thanks!

I used the standard dashboard from the guide. I put it in the dashboards folder in conf.

Is there a way I can supply more errors on what’s going on here? What throws me is that on start, it’s all peachy until I try to load.

This is my appdaemon.yaml:

AppDaemon:
  logfile: STDOUT
  errorfile: STDERR
  logsize: 100000
  log_generations: 3
  threads: 10
  time_zone: Europe/Stockholm
  api_port: 5000
  api_key: passwd
HASS:
  ha_url: https://my.host:8123
  ha_key: passwd
HADashboard:
  dash_url: http://my.host:5050
  dash_password: passwd

Hi,

I’m just getting started with HADashboard and got the same error. My configuration is basically the same as yours except for using !secret.

If I remove the dash_password configuration line the error is gone.

Perhaps someone with more knowledge about HADashboard can investigate more from here.

jenslj · September 25, 2017, 11:39am

Thanks!

That made the Dashbaords load as expected and I can carry on my testing. But it would be good for both of us to find out what’s up.

Thanks again för sharing!

I’m in the middle of a rewrite for portions of AD - when that’s done I’ll revisit and see whats up!

Just had the exact same problem. Removing the “dash_password:” solved it for me. Mostly the same error:

I’m having the exact same issue. Where you ever able to get it working?

jenslj · October 9, 2017, 7:16am

Well, No.

But removing the password is a decent workaround.

jabelone · October 9, 2017, 7:30am

Just stumbled upon this. Finished a fresh install just on armbian and I have exactly the same issue. The internal server 500 error disappears if you remove the “dash_password” line. For now I can just block 5050 in the firewall but it would be great to be able to put a password on it.

jwaymire · October 9, 2017, 3:20pm

Thanks, I’m currently using that work around however, I was just wondering if anyone got it working as I would like to make it accessible outside of the network.

ReneTode · October 9, 2017, 7:16pm

Andrew is working on a big update project at the moment.
i am sure thats also on his list of points to do.

jwaymire · October 9, 2017, 8:22pm

Thanks ReneTode. All in good time it is a great project though, excited for new updates.

wchan.ranelagh · November 7, 2017, 6:15am

I fixed this locally on my installation.

Not seeing anywhere where I can contribute fixes officially, but if someone let me know where I can do that, I’ll be happy to submit the fixes there.

In the meantime, for those who are interested, below are the lines you can update in the directory /usr/local/lib/python3.5/dist-packages/appdaemon (this is where my files are in raspbian; your exact directory may vary).

Hope this helps some folks out there so you can turn on the dashboard password again.

In rundash.py (line 70)

change

def forcelogon(request):
    return {"logon": 1}

to

def forcelogon(request):
    response = yield from utils.run_in_executor(conf.loop, conf.executor, conf.dashboard_obj.get_dashboard_list, {"logon": 1})
    return web.Response(text=response, content_type="text/html")

In dashboard.py (line 834)

change from

def get_dashboard_list(self):

    dash = self._list_dashes()

    env = Environment(
        loader=FileSystemLoader(self.template_dir),
        autoescape=select_autoescape(['html', 'xml'])
    )

    template = env.get_template("dashboard.jinja2")
    rendered_template = template.render(dash)

    return(rendered_template)

to

def get_dashboard_list(self, paramOverwrite=None):

if paramOverwrite is None:
    dash = self._list_dashes()
else:
    dash = paramOverwrite

env = Environment(
    loader=FileSystemLoader(self.template_dir),
    autoescape=select_autoescape(['html', 'xml'])
)

template = env.get_template("dashboard.jinja2")
rendered_template = template.render(dash)

return(rendered_template)

Hi there @wchan.ranelagh - thanks for looking into this - I would be happy if you would create a pull request against the appdaemon repository

When you do that I’ll merge it and put out a new version - I just haven’t had time to look at this because of the refactor I’m working on so this would be a great help.

EDIT: Never mind - I just copied it over and will be releasing a new version shortly.
