The automation worked before the release of 0.78 and the announcement of a the paid cloud service (not saying that is the issue)

I have the same issue with "AttributeError: 'NoneType' object has no attribute 'group'"

[rotcop4u2]

the post above solved my 'group' error!! thank you @cicero200272

[Molodax]

@rotcop4u2 , could you please elaborate how you solved it?

[rotcop4u2]

@Molodax i went to the post "https://github.com/home-assistant/home-assistant/issues/16749" and edited my gTTS-token.py file with this:

# -*- coding: utf-8 -*-
import calendar
import math

        if seed is None:
            seed = self._get_token_key()

        [first_seed, second_seed] = seed.split(".")

        try:

        except UnicodeDecodeError:

        return a

I am on a RPi 3B+ so i ran in the terminal:

python -m compileall /usr/local/lib/python2.7/dist-packages/gtts_token/gtts_token.py /usr/local/lib/python2.7/dist-packages/gtts_token/gtts_token.pyc

result was no more error. I am not home at the moment to check if the speaker activated and read the message. I will do in the morning and edit my post. But it is showing a progress bar on my speaker on the FRONTEND and executing my automation to completion. So I can probably call that a fix, without even needing to hear it.

[Molodax]

Thank you, @rotcop4u2 , now it is clear.
I'm using hassio, therefore, I will not be able to implement the fix in such way. Maybe it would be good to keep this issue open then?

[rotcop4u2]

@Molodax do you use samba at all for remote file access on your pc? or mac?

[Molodax]

I use Samba, however, it seems that I have no access to /usr/ on hassio unfortunatelly

[rpitera]

Same problem here, same error message. Also using hass.io so no hope for a DIY patch. Hope this gets resolved soon!

[ArnoutVerbeken]

Same issue here. No patch possible in hass.io.
This combined with https://github.com/home-assistant/home-assistant/issues/16686 makes a real mess of tts.google_say and cast since 0.78....
Hope this gets fixed with highest priority. You have basically broken everything that works with tts.google and/or cast....

[rpitera]

Tried rolling back to 0.77.3 but still not working. Guess I'll have to move over all my notifications to Alexa Media Player TTS for now.

[vladosam]

Until it's fixed try this.
Unpack this zip file with two folders to custom_components folder
gtts_token.zip
i tested this in docker but this should work in hassio too.
And don't forget to restart homeassistant.

[dshokouhi]

this is fixed in: https://github.com/home-assistant/home-assistant/pull/16775

[ArnoutVerbeken]

@rpitera @vladosam I also reverted back to 0.77.3 without any luck.
Afterwards I tried the fix of vladosam and everything works again now.

So on 0.77.3 with this fix, everything is up and running.

[ArnoutVerbeken]

@dshokouhi Thanks for the info. I hope they fix the cast issue also in 0.78.3. For now I stick to 0.77.3

[dshokouhi]

@ArnoutVerbeken the cast issue was fixed in 0.78.1 unless you still have the issue you need to provide your logs to the developers

[dshokouhi]

I see you did provide info, ok seems like a few people still have issues. Personally I just used a config entry and let my devices get discovered on their own.

[rpitera]

@vladosam - Giving it a try now. Will report back.

Update - Worked like a charm. I think I'm going to stay right here on 77.3 for a little while longer. See how things shake out since hass.io is still only at 0.78.1.

Thanks so much for the fix @vladosam and thanks @ArnoutVerbeken for the call out otherwise I might have missed it. Cheers to you both!

[vladosam]

@rpitera This fix works with 0.78.1 so go ahead and update. ;)

[ArnoutVerbeken]

@vladosam There are other issues when you want to use tts.goole_say with "Cast devices" (Google Home, Chromecast,...). So I wait untill that dust has settled down. I don't know if it is related to the cast issues, but I had to factory reset my Google Home today since it did not wake up when I said anything to it.

[AssuredDust640]

How exactly does one get to the gtts_token.py file to begin with?

[awarecan]

Fixed via #16775

Same. I updated to v1.1.3 of gtts-token and that resolved the issue.

[rotcop4u2]

I'm still on 1.1.2 and I am getting the same issue again
