I’m pretty sure I have same issue - Output from the log - hope this is useful, and thanks for your help

I think the error was same as above but I rolled back Hassio add-on to previous version so do not have the error log. I will roll forward again to test or if more info. Required

[skorokithakis]

I can't reproduce this right now, can someone post the versions of catt, PyChromecast and zeroconf that produce the above traceback? Looks to me like an upgrade broke things again.

[theychx]

The newest zeroconf release has a ton of changes, some of them apparently breaking pychromecast.

[scooper1]

Yes it's a upgrade of Hassio web terminal which has just been bumped to latest version
I am using latest version of Catt as this is installed automatically every time that add-on starts

[skorokithakis]

@theychx that makes sense. Can we pin to PyChromecast/zeroconf, since we recommend installing with pipx?

[scooper1]

Successfully installed PyChromecast-9.2.0 casttube-0.2.1 catt-0.12.1 protobuf-3.17.3 youtube-dl-2021.6.6

[theychx]

Yep, 9.2.0 & 0.31.0

[skorokithakis]

I see that PyChromecast doesn't pin either, so we'd have to list zeroconf as a dependency... Not a great solution, and pinning PyChromecast itself wouldn't help with this. Maybe we can start pinning PyChromecast and urge them to pin zeroconf on their end?

Either way, I will close this ticket because it's an upstream issue. Thanks to everyone for their help!

[scooper1]

installing with startup option "python3 -m pip install catt" pipx is not available in this docker image

[skorokithakis]

pipx isn't needed for Docker, since it's already self-contained.

[theychx]

@skorokithakis

so we'd have to list zeroconf as a dependency

At the moment, there is no way around that, if we want to make a working release.

[skorokithakis]

Yeah, I'm afraid you're right... I have left a comment on the PyChromecast issue, but I guess we should pin now and worry later.

[lolouk44]

I have the same issue but can't see above how to resolve this on my HA docker container installation?
Can anyone recommend a workaround? I tried to reinstall catt but still get the issue...

[scooper1]

you have to do a partial restore just doing that docker container
hope you got backups ....

[lolouk44]

Thanks. Can you elaborate?
I run ha in a container so I guess I could always restore the previous version. What do I need to recover / bring over to the new container please?

[scooper1]

thinking a bit more - if you are using web and terminal then role back to 8.24 by just restoring that addon
if you are installing in the hassio runtime system then you will have to go back to 2021.6

[J-o-h-n-M]

My solution, for now, is that I reverted back to this docker 2021.6.6 . I just used Portainer to get this version and I did not need to restore anything. Afaik nothing broke with the downgrade.

Thanks. I'll temporarily go back to 2021.6
Now since this really is a bug, should this issue be reopened? And is it going to be fixed so it can work on 2021.7 and up? Or is this a home assistant issue and if so is it tracked somewhere?

[skorokithakis]

This is a zeroconf/pychromecast issue but I will publish a workaround.

[skorokithakis]

I have published v0.12.2 which should fix this, please test and report back.

[J-o-h-n-M]

I have published v0.12.2 which should fix this, please test and report back.

Just updated to "homeassistant/home-assistant:latest" docker and then updated Catt to v0.12.2. Works like a charm!. Thanks for the quick update.

[scooper1]

Working
Thank you for updating

[lolouk44]

Thanks I can also confirm that catt 0.12.2 fixes
(though I had to manually set the version to 0.12.2 with python3 -m pip install catt==0.12.2 for some reason )

[tobip]

Since the last update on my system I also get this error.

catt version v0.12.1-2
python-pychromecast 9.2.1-1
python-zeroconf 0.36.4-1

All of them installed through AUR.

[MarcelRobitaille]

I am still getting this error in 0.12.2.

I get this error when doing catt scan. Strangely, I called that once with no chromecasts on my network and it printed Error: No devices found. I connected the chromecast to the network and ran it again and it listed my chromecast successfully, but the third time I tried to run it (after renaming the chromecast in the google home app, if that changes anything) I get this error.

Here's the error in a code block so it's a bit easier to read.

catt --version reports catt v0.12.2, Zaniest Zapper. although the AUR package version still says 0.12.1.r7.g0519e00-1 for some reason. System Python version is 3.9.7.
