Erroneous JSON: Connected

Metus88 opened this issue 4 years ago · 12 comments

I updeted the plugin.
After in my home assistant log file appears:
2020-10-18 18:14:47 WARNING (MainThread) [homeassistant.components.mqtt] Erroneous JSON: Connected 2020-10-18 18:14:47 WARNING (MainThread) [homeassistant.components.mqtt] Erroneous JSON: Connected 2020-10-18 18:14:47 ERROR (MainThread) [homeassistant.helpers.template] Error parsing value: 'value_json' is undefined (value: Connected, template: {{value_json._event}})

So I activated the debug to have more information.

I don't understand how to solve the problem. Is there some problem with the message "Connected"? and "value_json._event"?

Am I the only one to have this problem?

any news?

Hello. I too have the same error appearing in log.

Answer 2 · 2020-10-20T13:55:17.000Z

I tried to delate my MQTT retained with these guide. I deleted the file mosquitto.db and maybe the error disappeared. (Better say: it disappears for now).

EDIT:
It appears again:

Answer 3 · 2020-10-30T12:28:50.000Z

I'll take a look this weekend. In the mean time would you goto your integrations, MQTT, and the device for your printer. There is a link for "MQTT Info", could you paste the configuration used for the connected sensor please.

Thanks for the report.

Answer 4 · 2020-10-30T13:23:43.000Z

Sorry for the formatting but I not able to do better. Sorry for the Italian language in some part of the info.
And I don't know if I have to expand all

I updated, but is it possible that the problem is not fixed?

Do I have to delate mqtt integration and add the printer again?
Do I have to reinstall mosquito mqtt server?

Answer 6 · 2020-10-30T14:28:59.000Z

You should only need to delete the device, and then restart octoprint (to re-register it). I think there is something stuck in the UI cache that leads to this... there is not json using templates now so I don't see a reason for the error.

Answer 7 · 2020-10-30T15:11:40.000Z

Thanks! I tried to delete the device but without change name, the error still remains.
To fix my problem I deleted the mosquito database. I followed this instruction .

sudo systemctl stop mosquitto.service
sudo rm /var/lib/mosquitto/mosquitto.db
sudo systemctl start mosquitto.service

Answer 8 · 2020-10-30T17:29:26.000Z

I'm sad, the problem is still there.... I delated all my maria database, all my mosquito mqtt server, all my integration.... I uninstalled the plugin from octoprint and I reinstalled it but the error is still there...

Answer 9 · 2020-10-30T17:32:17.000Z

I'll see what happens on my printers this weekend. But I'm guessing there is something wrong with the sensor config schema we simply cannot see from the UI.

Answer 10 · 2020-10-30T17:38:27.000Z

thanks, I tried also to edit the file in /home/pi/oprint/lib/python2.7/site-packages/octoprint_homeassistant/init.py editing the words "Connected" vs "connected" but no luck... Thanks again

Ok, so this is an unrelated error that was introduced on #39 . I have a fix incoming shortly.
