Implicit Invocation of Google Assistant Action App with DialogFlow not working - json

Question

I'm getting the
"API Version 2: Failed to parse JSON response string with 'INVALID_ARGUMENT' error: \": Cannot find field.\"."
and so am hoping you can help me, as I cannot get Implicit Invoking working for my app.
I've attached screenshots of the Welcome Intent setup on DialogFLow as well as pasted the Google Cloud fail logs here:

Answer 1

The issue is because the intent you are trying to match "Log call by name" which expects an input context "sessionData", will never be matched because invoking your app using a deep-link "ask follow up to log a call" doesn't send that context in the request. That explains why your default response (Text response) for that intent isn't returned.
To fix it you need to:
Remove the input contexts from the intents you intend to use as deep-links OR duplicate those intents and remove the input contexts from the duplicates.
Best practice 1: Have a fallback intent that has no input contexts, which will catch any unmatched in-dialog queries.
Best practice 2: Have a fallback intent that specifically handles unmatched deep-links at invocation time. (See image below)

Answer 2

The agentToAssistantJson field has an encoded JSON entry for result which typically suggests that your webhook isn't returning anything. Normally, Dialogflow returns the static messages you've defined in the Intent in this case, but it sounds like that isn't happening here. Verify that the URL you're using for fulfillment is correct and that it is returning valid JSON.
In this case, I think there are a few things that could be causing the problem.
The phrase "Ask follow up to log a call" should be triggering the Log Call by Name Intent it looks like. But this Intent isn't listed as one of the implicit invocation Intents. The Assistant might be passing this off to Dialogflow, and Dialogflow, finding no match, returns nothing.
But even if it did match the phrasing for the Log Call by Name Intent, and that Intent was an implicit invocation Intent, there are two other elements of the Intent that seem strange.
The first is that the Intent is expecting an input context of sessionData. But since this is meant to be used as an initial Intent, there can be no input context. Dialogflow may be told by the Assistant that this is the matching Intent, and then reject it because the input context doesn't match.
Similarly, the second oddity is that you're looking for an event called CALL_BY_NAME. Events generally override any phrases that may be spoken - they're meant to capture non-textual activities (the WELCOME intent, for example, or an option being selected, or the user saying nothing). Unless you're triggering the event (which you can do), you probably wouldn't want it. As above, I'm wondering if the Assistant is telling Dialogflow this is the Intent to use, but Dialogflow isn't getting the event, so rejects it and sends back nothing.
tl;dr
There are three possible things to look at and fix:
Make sure the Intent is listed as an implicit invocation Intent in the Assistant Integration.
Remove the incoming context.
Remove the event.
