Passing Parameters to Contexts

[arielschvartz]

When passing parameters to a new contexts (via createContext or detectIntent), you cannot just passa an object.

For example:

contextsClient.createContext({
  parent: sessionPath,
  context: {
    name: "projects/my-project-id/agent/sessions/my-session-id/contexts/my-context-name",
    lifespanCount: 1,
    parameters: {
      foo: "bar"
    }
  }
})

In the above example, the foo parameter is not set in the context. For it to work you should pass like:

contextsClient.createContext({
  parent: sessionPath,
  context: {
    name: "projects/my-project-id/agent/sessions/my-session-id/contexts/my-context-name",
    lifespanCount: 1,
    parameters: {
      fields: {
        foo: {
          stringValue: "bar"
        }
      }
    }
  }
})

As solution, I think the better way would be for the lib to handle that and convert. The other way of resolving this problem would be simply updating the documentation.

By the way, I didn't find anywhere in the Dialogflow documentation the possible values for a field (like stringValue). Is there something like numberValue, datetimeValue?

Hope it help other people! =)

Just discovered that exactly the same applies to passing parameters to the payload of the detectIntent.

👋 @arielschvartz this looks like a duplicate of #97, which is a fairly common complaint we get here. The client itself is actually generated, so I think getting a feature like this in will be tricky and probably take some time (although I do believe it is on our radar).

In the mean time we've been suggesting using pb-util to convert protobuf structures like this.

Thank you very much @callmehiphop ! Gonna use the lib for now!

But I suggest adding it to the docs in the dialogflow website! Would be simples and help a lot of people!

@arielschvartz thanks for the suggestion!

@bcoe any idea how we can do a better job of documenting this? Seems like a common point of frustration for users here, but I'm not really sure how to solve the issue since everything for Dialogflow is generated.
