issue with aws service discovery javascript

[Ravi-Rsankar]

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;
        ^

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

@Ravi-Rsankar thanks for opening the issue, transferring it to the correct repo. https://github.com/aws/aws-sdk-js-v3

Same issue here when bumping @aws-sdk packages from 3.36.x to latest.... Do you have any updates. please?

[brunobasto]

Same here. Anyone found a solution?

Update (May 23, 2022) - Bump to v3.95 across the board of all the services we are using brings no changes.

    TypeError: Cannot destructure property 'readFile' of 'fs_1.promises' as it is undefined.

@ajredniwja My apologies for tagging you directly here. I'm desperately looking for any updates about the issue, since currently we are stuck at a really old version of AWS SDK and cannot upgrade because of the build failures.

Also, had anybody here found any workaround for that?

Facing the same issue with @aws-sdk/client-s3 on AWS CodeBuild with nodejs v14. Local builds with nodejs v14.15.x still working.

[dopedwolf]

@mbunge Did you find a solution to this?

[ajredniwja]

This is possibly related to https://github.com/aws/aws-sdk-js-v3/issues/3828

Any updates?

Hi guys, I'm using two AWS packages:

"@aws-sdk/client-secrets-manager": "^3.282.0"
"@aws-sdk/client-ssm": "^3.282.0"

Node.JS version 16.19.1 and I'm also facing this error, it's like:

  TypeError: Cannot destructure property 'writeFile' of 'fs_1.promises' as it is undefined.

      1 | const Confidence = require('confidence')
    > 2 | const { SecretsManagerClient, GetSecretValueCommand } = require('@aws-sdk/client-secrets-manager')

I was testing a possible fix locally and I needed to change, from:

const fs_1 = require("fs");
const { writeFile } = fs_1.promises;

to (I saw it on that TODO):

const fs_1 = require("fs/promises");
const { writeFile } = fs_1;

In three files:

• writeSSOTokenToFile
• slurpFile
• getSSOTokenFromFile

After it I got success on the tests that I was running.

Can anyone help, applying those changes on the SDK?

I've just realized that I was mocking fs in my test:

jest.mock('fs')

I changed to use jest.spyOn(fs, 'writeFileSync').mockReturnValue({}), now it's working!

[zterlizz]

You can also mock the 'fs' module and retain functionality using jest.requireActual() like this:

const fs = require('fs');

jest.mock('fs', () => ({
  ...jest.requireActual('fs'),
  openSync: jest.fn(),
  createReadStream: jest.fn(),
  writeFileSync: jest.fn(),
  writeSync: jest.fn(),
  closeSync: jest.fn()
}));

All 'fs' functionality will remain and only the listed functions will be mocked: openSync, createReadStream, writeFileSync, writeSync, closeSync.
