issue with aws service discovery javascript

Question

Im developing a nodejs application that needs to register to the AWS service discovery on the app start. I'm using the @aws-sdk/client-servicediscovery lib in my node application. As a reference, I am using the code from here: https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/clients/client-servicediscovery/index.html.

const { ServiceDiscoveryClient, CreateHttpNamespaceCommand } = require("@aws-sdk/client-servicediscovery");
const client = new ServiceDiscoveryClient({ region: "xxx" });
const params = {
    "ServiceId":"xxx",
    "InstanceId":"xxx",
    "CreatorRequestId":new Date(new Date().toUTCString()),
    "Attributes": {
        AWS_INSTANCE_IPV4: "xxx.xx.xx.xx",
        AWS_INSTANCE_PORT: xxx,
        service: "xxx",
      }
};

const command = new CreateHttpNamespaceCommand(params);
client.send(command).then(
    (data) => {
      console.log(data)
    },
    (error) => {
        console.log(error)
    }
  );

While running the app, getting these errors.

/application/node_modules/@aws-sdk/shared-ini-file-loader/dist-cjs/slurpFile.js:5
const { readFile } = fs_1.promises;
        ^

TypeError: Cannot destructure property `readFile` of 'undefined' or 'null'.

I am new to the AWS SD so need some help registering my service to the service discovery. Thanks in advance!
