WTH Google Chat - Repeating messaages

After running for a day or so, Google Chat repeats messages from intent scripts but not from automations.

I love the Google Chat notifications. Our family and friends use the application for all of our communication.

I have several automations to tell me when batteries are low or someone is at the door etc, these work fine. I also use intent scripts for getting current temperatures and forecast etc, these repeat. The repeat messages can be fixed by rebooting the system (which has been added to the intent scripts).

This issue has been posted several times in GitHub but the post has gone stale before action has been taken.

PS I love a good #WTH and the work you guys do. Thank you.
