Error: 3 INVALID_ARGUMENT: Name 'Hello' does not match patterns DialogFlow

Question

I am working on a project with DialogFlow V2 Api using Nodejs and the following code somehow does not seem to work:

    var query = req.body.query;
    const request = {
      session: sessionPath,
      queryInput: {
        text: {
          text: query,
          languageCode: 'en-US',
        },
      },
      queryParams: {
      contexts: [
          {
            "name": "Question-followup",
            "parameters": {},
            "lifespanCount": 0
          }
        ]
      }
    };

    // 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);
      });

And the error I recieve is:

ERROR: { Error: 3 INVALID_ARGUMENT: Name 'Question-followup' does not match patterns 'projects/{projectId=}/agent/environments/{environmentId=}/users/{userId=}/sessions/{sessionId=}/contexts/{contextId=},projects/{projectId=}/agent/sessions/{sessionId=}/contexts/{contextId=}'.

Note: I do have "Question-followup" context into an Intent, so it should not be the problem that the context does not exists or something!

Any idea what would this be?

You need to include the full path to your context. The Dialogflow v2 Node.js library has a helper method to construct the context path for you.

contexts: [
      {
        "name": contextsClient.contextPath(projectId, sessionId, "Question-followup"),
        "parameters": {},
        "lifespanCount": 1
      }
    ]
