Error Config flow could not be loaded

[marcschachtsiek]

I have tried installing this integration by using HACS and manually, but both times I get this error. I am fairly new to Home Assistant and this is the first integration that I am trying to install. I'm using the docker installation on an RPi 4.

This is the full error log output.

This error originated from a custom integration.

This is probably caused by your Home Assistant not having access to BLE hardware. Try using gatttool from your HA container and make sure it is working first.

[agonzale34]

I'm getting the same error in the logs with a different message:
Error
Config flow could not be loaded: 500 Internal Server Error Server got itself in trouble
I'm running HA on a container on raspberry pi 4 with raspbian 64bits

[agonzale34]

I did run the gatttool commands successfully inside the container

[Aaron19953]

I'm having the same issue as @agonzale34 , running HA in Docker. I can confirm that HA recognizes the BLE hardware because the bluetooth device tracker is working fine.

[sysofwan]

Please share your log output, the issue may not be the same. I am using the bleak library, so you can test if that works in containers or not too.

I have a similar issue. This is the error message:

In the HA terminal, I can see the device and I can connect to it, but the integration is not installing...
Also I have these in the log:

File "/config/custom_components/triones/config_flow.py", line 37, in async_step_user
    devices = await discover()
  File "/config/custom_components/triones/triones.py", line 13, in discover
    devices = await BleakScanner.discover()

Could you help me please?

[lyfesaver74]

Any news on this?

[simplelnx]

For me the issue is that bleak is not working inside HomeAssistant docker container. Tested using a standalone python script.
Does anyone know how to fix bleak? I am running the latest 2022.7.4 version of HA

[jonrodrigues42]

Having the same issue here (i'm using HomeAssistant docker container, Ubuntu Server 22.04), has anyone figure it out?

[dharvey242]

I've got this issue. When using terminal and list bluetooth devices, the triones device is found. However the integration fails to load. I've removed and reinstalled and still nothing. It was working fine but not sure on what HA release it failed. I'm on the latest version of HA - 2023.9.1

I'm also getting 500 when starting the config flow. This is the error from the logs:
