hi,

I am trying to add the knowledge beta but I am getting an error

error:

UnhandledPromiseRejectionWarning: TypeError: match error: could not instantiate a path template from projects/botkit-a4598/knowledgeBases/projects/botkit-a4598/knowledgeBases/NzU0ODk2NTM2LOMzMzMwNTM0NA
    at PathTemplate.match (/home/****/project/demo/node_modules/google-gax/build/src/pathTemplate.js:99:19)

code:

const dialogflow = require('dialogflow');
const uuid = require('uuid');

module.exports = {
  know:async function(
  projectId,
  sessionId,
  languageCode,
  knowledgeBaseFullName,
  query,
  error
) {
  // [START dialogflow_detect_intent_knowledge]
  // Imports the Dialogflow client library
  const dialogflow = require('dialogflow').v2beta1;

  // Instantiate a DialogFlow client.
  const sessionClient = new dialogflow.SessionsClient();

   projectId = 'botkit-a4598fgh';
   sessionId = `12345`;
   languageCode = 'en-US';
   knowledgeBaseFullName = `projects/botkit-a4598fgh/knowledgeBases/NzU0ODk2NTM2MTMzMzMwNTM0NA`;
   query = `How can I track my orders & payment?`;

  // Define session path
  const sessionPath = sessionClient.sessionPath(projectId, sessionId);
  const knowbase = new dialogflow.KnowledgeBasesClient();
  const knowledgeBasePath = knowbase.knowledgeBasePath(
    projectId,
    knowledgeBaseFullName
  );

  // The audio query request
  const request = {
    session: sessionPath,
    queryInput: {
      text: {
        text: query,
        languageCode: languageCode,
      },
    },
    queryParams: {
      knowledgeBaseNames: [knowledgeBasePath],
    },
}
if(error)
{
  console.log(error);
}
const responses = await sessionClient.detectIntent(request);
  const result = responses[0].queryResult;
  console.log(`Query text: ${result.queryText}`);
  console.log(`Detected Intent: ${result.intent.displayName}`);
  console.log(`Confidence: ${result.intentDetectionConfidence}`);
  console.log(`Query Result: ${result.fulfillmentText}`);
  const answers = result.knowledgeAnswers.answers;
  console.log(`There are ${answers.length} anwser(s);`);
  answers.forEach(a => {
    console.log(`   answer: ${a.answer}`);
    console.log(`   confidence: ${a.matchConfidence}`);
    console.log(`   match confidence level: ${a.matchConfidenceLevel}`);
  });
  // [END dialogflow_detect_intent_knowledge]
}

Hi @sarigasurendranms it looks like there's an issue with how you're calling knowledgeBasePath(). In your example you're passing the full name as the second parameter but it is expecting just NzU0ODk2NTM2MTMzMzMwNTM0NA.
