We built a Dialogflow agent using google cloud functions as webhook which worked properly until yesterday evening. At that time I exported the agent and reimported it later on and it worked for a while.
What stopped working is that agent.context.get('...'); (also agent.getContext('...')) does return undefined even if the context is set according to the UI and raw API response.
As an example I have an intent which has a required slot shop, webhook for slot filling enabled.
When I test the agent, the intent named info is matched correctly and also the context info_dialog_params_store seems to be there:
And here is part of the output context according to the raw API response:
"outputContexts": [
{
"name": "projects/MYAGENTNAME/agent/sessions/0b753e8e-b377-587b-3db6-3c8dc898879b/contexts/info_dialog_params_store",
"lifespanCount": 1,
"parameters": {
"store": "",
"store.original": "",
"kpi": "counts",
"date_or_period": "",
"kpi.original": "trafico",
"date_or_period.original": ""
}
}
In the webhook I mapped the intent correctly to a js function:
let intentMap = new Map();
intentMap.set('info', info);
agent.handleRequest(intentMap);
And the first line of the info function looks like:
function info(agent) {
store_context = agent.context.get('info_dialog_params_store');
}
Which returns
TypeError: Cannot read property 'get' of undefined

I am quite sure that I did not change anything which could affect the proper functioning of agent, except some refactoring.
I also tried the beta functions activated as well as deactivated as I read that there can be issues with environments, but that did not change anything.
Anyone knows in which direction I can investigate further?

Enable fulfillment responseNavigate to the Dialogflow console and click Intents. Click Schedule Appointment Intent. Scroll down to Fulfillment and turn on Enable webhook call for the intent.
When you enable fulfillment for an intent, Dialogflow responds to that intent by calling a service that you define. For example, if an end-user wants to schedule a haircut on Friday, your service can check your database and respond to the end-user with availability information for Friday.
You can call an intent directly without any prompt to user with the help of events . From the fulfillment, you can invoke an event with the help of followupEventInput . Just make sure to give correct name of event under your intent in Dialogflow console.
Input and output contexts are applied to intents. They work together to control conversation flow: Output contexts control active contexts. When an intent is matched, any configured output contexts for that intent become active. Input contexts control intent matching.
I had the same issue, I resolved it updating dialogflow-fulfillment in package.json:
from "dialogflow-fulfillment": "^0.5.0" to "dialogflow-fulfillment": "^0.6.0"

I solved the problem by turning off "Beta features" enter image description here
