• Expected: no error, at least a useful error message, and no javascript dumps on stdout

• Problem-relevant configuration.yaml entries and steps to reproduce:

1. install homeassistant=0.62.1
2. (re)move your existing config, so ~/.homeassistant/ does not exist
3. start hass
4. open webinterface

• Additional info: this first occured to us on another instance, so probably not limited to OS or client browser version reported here

[azrdev]

Looks like this is fixed with homeassistant-0.64.3 (from pip)

[fakezeta]

Hi @azrdev can you confirm? I just updated homeassistant with Firefox 58.0.2 and still have the same error.

[azrdev]

@fakezeta as I said, I don't see it anymore with 0.64.3 -- what's your version? (I'm also on firefox 58.0.2, to rule that out)

[fakezeta]

I'm running Docker image 0.64.3 from https://hub.docker.com/r/homeassistant/home-assistant/

BTW I've also tried cleaning cache, cookies and all the usual stuff.

[ghost]

For me the same problem persists in 0.64.3 and Firefox 58.0.2 on a RPi2 with hassbian.

In addition I usually cannot access the 'developer tools' in the webUI. When I can I see the error repeatedly written into the logs.

I had this issue before in 0.64.1. It disappeared in 0.64.2 and then reappeared in 0.64.3.

Any suggestions what could be wrong? Will this be fixed?

@azrdev Can you reopen this issue? It is certainly not solved for me.

I also played around with javascript_frontend: auto/latest/ES5 which did not help.

UPDATE: Seems to be solved with Firefox 59.0 on Windows 10.

[fakezeta]

Update: I just updated Firefox to 59.0 on Windows 7 (still not tested on macOs) and the issue seem solved with hass docker image 0.65.3.

@darioce can you check?
