I have followed all the steps of this tutorial but when I want to test it on my computer, it shows the following error: “Sorry, Place Finder isn’t responding right now. Please try again soon.” Could anyone help me, please?
Hello, this error is from Google, not Rasa.
Try asking on Stack Overflow, you’ll have better chances 
I have another question, in step 4 the class is defined as “GoogleAssistant” but in the full code is defined as “GoogleConnector”, does it make any difference to the final result?
Thank you very much in advance!
Yeah, it should be GoogleAssistant.
The class name doesn’t really matter though, what matters is the return "google_assistant".
