Tts.google_say errors 'NoneType' object has no attribute 'group'

Hi guys, I recently started working with HA (running on RPi 3B+ with raspbian stretch in docker). All worked fine but google tts seems to be broken now.

The error that I get:

Log Details (ERROR)

AttributeError: 'NoneType' object has no attribute 'group'

After searching the web I found a possible solution:
https://github.com/instabot-py/instabot.py/issues/1529
which pointed to this:
https://github.com/instabot-py/instabot.py/commit/806e09414f73a461bdb81fd6d4fc2e1e34a54ef8

Any thoughts on how to do this when using HA in a docker container?

Known issue, possible solution gTTS-token update.

thanks! didn’t find it somehow.

For people who find this topic first. This worked for me:
I went into the console of my HA docker container (I use portainer) and executed:

pip uninstall gTTS-token
pip install gTTS-token

Then restarted HA and tss is working again

This is broken again now, but I have a fix in pull request. A working version of the gtts_token can be found here:

# -*- coding: utf-8 -*-

    """ Token (Google Translate Token)
    Generate the current token key and allows generation of tokens (tk) with it
    Python version of `token-script.js` itself from translate.google.com
    """

    SALT_1 = "+-a^+6"
    SALT_2 = "+-3^+b+-f"
    TKK = 'tkk:'  # the way the token is identified in page

    def __init__(self):
        self.token_key = None

I have been in the process of moving my setup from a Pi at 0.75.1 to a Docker setup on 0.82.1, and I thought I had something messed up in the config for the last hour. Should have searched here first.

Thank you for the update, just used the old custom_component from here, Google TTS Problems and updated the gtts_token.py with your new code for now, and all back working again.
