Error when using “importAgent” interface of dialogflow (node.js)

Question

I am using Dialogflow client on my Node.js server to import-agent using.zip file which I got from exporting agent through dialogflow console. This is the implementation -

const dialogflow = require("dialogflow");
const fs = require("fs");

const zipFile = "./exported_agent.zip";
const credentials = require("./credentials.json");

async function importAgent() { 
  try {
    // converting zip file to base64 format
    const base64ZipFile = await fs.readFileSync(zipFile).toString("base64");

    const client = new dialogflow.v2.AgentsClient({
      credentials,
      agentContent: base64ZipFile,
    });

    const formattedParent = client.projectPath("[PROJECT-ID]");

    [operation] = await client.importAgent({parent: formattedParent});
    [response] = await operation.promise();
    
    console.log(response)
  } catch(err) {
    console.log(err)
  }
}

importAgent()

But I am facing this error

Error: 3 INVALID_ARGUMENT: com.google.apps.framework.request.BadRequestException: Invalid agent zip. Missing required json file agent.json

    internalRepr: Map(1) { 'grpc-server-stats-bin' => [Array] },
    options: {}
  }
}

On unzipping the.zip file, I can clearly see agent.json file. I have tried directly importing-agent (using same.zip file) through dialogflow console, it is working fine. But it is showing above error when I am trying to do it with the dialogflow client. I am following this .

I appreciate any ideas on how can get this working again. Thanks!

I think all you need to do is move the agentContent setting from your .AgentsClient() call to your .importAgent() call - the example in those docs is incredibly bad, as it never shows actually setting agentContent or agentUri in the importAgent call, despite one of them being required!
