i have some problems with my node code. I am building an action-on-google with api.ai, node.js and a webhook on Heroku.
The problem is that I want to an Argument out of a context, but I only get errors.
When I use getContexts there is not problem as you can see in the logs
let input = assistant.getContexts();
When I try getContext or getContextArgumet i get a type error.
let input2 = assistant.getContextArgument("csearch", "query");
I looked at the documenation, github and examples, but I don't know what exactly is wrong with my code. The name of the parameters should be allright (compare with the json) and the functions should ok as well https://developers.google.com/actions/reference/ApiAiAssistant#getContextArgument
I hope someone could take a short look on it.
So, first of all, the JSON:
{
"id": "c2519421-0a7a-466c-99dc-b5d84949a74f",
"timestamp": "2017-04-19T15:54:04.627Z",
"lang": "de",
"result": {
"source": "agent",
"resolvedQuery": "ne",
"action": "queryNext",
"actionIncomplete": false,
"parameters": {},
"contexts": [
{
"name": "csearch",
"parameters": {
"query": "wurst",
"query.original": "wurst"
},
"lifespan": 3
},
{
"name": "cquery",
"parameters": {
"query": "wurst",
"query.original": "wurst"
},
"lifespan": 5
}
],
"metadata": {
"intentId": "e12d2e09-23fa-45ba-891d-5832f711b811",
"webhookUsed": "true",
"webhookForSlotFillingUsed": "false",
"intentName": "recipe_search_next"
},
"fulfillment": {
"speech": "Nächstes Rezept",
"messages": [
{
"type": 0,
"speech": "Nächstes Rezept"
}
]
},
"score": 1
},
"status": {
"code": 206,
"errorType": "partial_content",
"errorDetails": "Webhook call failed. Error: Webhook response was empty."
},
"sessionId": "5178e4a6-af77-4710-bafe-2908609225e3"
}
As you can see, my webhook throws an error. But take a look at contexts. This is the data I want to get.
My node.js code snippet
function placeholderFunction (assistant) {
/// PLACEHOLDER FUNCTION TO TEST
let input = assistant.getContexts();
console.log("Die Ausgabe für den gesamten Kontext", input );
let input2 = assistant.getContextArgument("csearch", "query");
console.log("Die Ausgabe für den speziellen Kontext", input2 );
assistant.tell("Placeholder - keine Fehler in der Response. (Siehe Logs für mehr)");
}
And finally my log:
2017-04-19T15:45:51.366142+00:00 app[web.1]: Die Ausgabe für den gesamten Kontext [ { name: 'csearch',
