Rest sensor not working after installing Home Assistant Core

[Christian-PK]

The problem

Hello, I have a problem with the rest sensor and httpx. When i set the configuration as below i get an attribute error. I have tried the home assistant docker image on another vm for test with the same configuration file and it works on the docker image. But i do not wish to run on docker.

I Installed Home Assistant Core on a fresh Ubuntu server live 20.04 last week. I tried to reinstall httpx with pip3 but same result. I have run apt update and apt upgrade. I tested i can access the url with curl

Any suggestions?

core-2021.4.6

First, you are using an old style config. Check dokumentation om how it should look.

Second i think you have wrong httpx version or one of its dependencies are wrong. Please remove the python virtual env you are running it in and recreate it. Running without a python env is not a working solution.

[Christian-PK]

if i run pip3 freeze then it shows i am running httpx 0.18.0, is that the right version?

I am not sure if i did it correct but to delete and create the virtual environment i ran the following commands: cd /srv/homeassistant

• Delete the environment sudo rm -rf venv
• Create environment sudo -u homeassistant -H -s python3.8 -m venv . source bin/activate

still the same result.

[elupus]

Nope looks lit it should be 0.17.1. so you have some component that pulls in 0.18.0

[Christian-PK]

So i changed to 0.17.1 but still no difference

[elupus]

Have you fixed the config?

[Christian-PK]

Is it the specific sensor or the hole configuration.yaml. I can not see any difference in the documentation and my files.

[elupus]

Check the rest sensor documentstion linked above.

You have the config under: sensor/platform: rest. It should now be under rest/sensor.

[bdraco]

It looks like your httpcore version is too new to use with 0.17.1

https://github.com/encode/httpcore/releases

Downgrade httpcore to 0.12.3

[bdraco]

I tested httpx 0.18.0 with httpcore 0.13.0 and everything worked with rest.

I opened a PR to bump httpx to 0.18.0 here: https://github.com/home-assistant/core/pull/49805

[Christian-PK]

Changing the config did not change anything still same error

Configure a default setup of Home Assistant (frontend, api, etc)

default_config:

Text to speech

tts:

• platform: google_translate

group: !include groups.yaml automation: !include automations.yaml script: !include scripts.yaml scene: !include scenes.yaml

rest:

• resource: http://ip.jsontest.com sensor:
  • name: External IP value_template: "{{ value_json.ip }}"

I will try downgrade httpcore

[Christian-PK]

I destroyed the packagedependencies. So i deleted /srv/homeassistant and installed again, and now i works. Unfortunatley we will never know what the problem was.

Thanks a lot for you help.
