Invoking my Google action produces inconsistent results. Sometimes it'll work normally, and sometimes it'll just say "app isn't responding right now. Try again later."

When it doesn't respond, the error in Stackdriver logs states:

MalformedResponse: ErrorId: 9d77f434-ed3c-485b-9531-05449ee83c29. Failed to parse json into AppRequest proto. com.google.protobuf.InvalidProtocolBufferException: Cannot find field: canvasContext in message google.actions.v2.Input

This error has happened on the google home, google home mini, and the Lenovo smart display. It happens most on the smart display. And it hasn't happened yet on a mobile device.

I see exactly the same error in some of our customer projects. For me it looks like a Google hiccup because our AoGs with that error in the logs does not even use Canvas.

  • It really does seem like a hiccup as some other production apps on the store also occasionally went unresponsive. The issue also seems to have stopped out of the blue the very next day. I'm really curious to find out what caused a request for something called "canvasContext." I'm also a little paranoid that the issue will surface again. – Wahuu Jun 13 '19 at 20:46
