how do I send a context parameter to the webhook/fulfilments DialogFlow v2

Question

I am reading the official documentation from this link: https://cloud.google.com/dialogflow-enterprise/docs/reference/rest/v2beta1/QueryParameters but I am unable to pass a context parameter into my request using the following code:

  var query = req.body.query;
    const request = {
      session: sessionPath,
      queryInput: {
        text: {
          text: query,
          languageCode: 'en-US',
        },
      },
      queryParameters: {
        contexts: ['Question-followup']
      },
    };

    // Send request and log result
    sessionClient
      .detectIntent(request)
      .then(responses => {
        const result = responses[0].queryResult;
        console.log(result);
        res.json(result);   
        if (result.intent) {
          console.log(`  Intent: ${result.intent.displayName}`);
        } else {
          console.log(`  No intent matchede.`);
        }
      })
      .catch(err => {
        console.error('ERROR:', err);
      });

In the documentation it says that I should have something like:

"contexts": [
    {
      object(Context)
    }
  ],

The reason I want this is that sometimes DialogFlow is not able to detect the Intent so I would think that by passing the context into the parameter would help dialogflow to find the correct intent!

The contexts array needs to be an array of Context objects, not just a string with the context names.

The context object looks something like

{
  "name": "projects/<Project ID>/agent/sessions/<Session ID>/contexts/<Context Name>",
  "lifespanCount": 1,
  "parameters": {
    "anyParameterName": "parameterValue"
  }
}

I no longer get the error, which seem to fix, but one thing I dont get is, why does not detect the right intent when I give some input, what I mean I would like to force the user whatever is writing redirect to a specific intent, is this possible? I thought by passing the context name would do the work, but it doesnt! instead it is detecting the intent by input text – Mizlul Jun 06 '18 at 11:22
I will accept this answer, as it fixes the problem I had with giving the right parameters, but still I would like to know how do I redirect user input to a specific Intent regardless their input. – Mizlul Jun 06 '18 at 11:31
I'd suggest asking this as a new question directly - it isn't clear what you're trying to do and why it isn't working, so some examples (screen shots of the Intents and results, etc) would help. – Prisoner Jun 06 '18 at 14:37
Thanks, I am using dialog flow CX what should be the context ? – Aymal Jul 17 '22 at 09:28
Dialogflow CX handles this completely differently. You should post a new question with as much detail as possible about the issue you're having and tag it `dialogflow-cx` – Prisoner Jul 17 '22 at 10:26
