Upgrade to AWS SDK v3.25.1 to Resolve Authentication Token Error

Medium Risk

The error 'Request is missing Authentication Token' is caused by a regression in the AWS SDK version 3.25.0, which affects the authentication mechanism during deployment. This issue has been identified by the maintainers and is resolved in version 3.25.1.

Awaiting Verification

Be the first to verify this fix

  1. 1

    Upgrade AWS SDK to v3.25.1

    Update your AWS SDK version in your project to the latest patch version (3.25.1) to resolve the authentication issue caused by the regression in the previous version.

    bash
    npm install aws-sdk@3.25.1
  2. 2

    Verify serverless.yml Configuration

    Ensure that your serverless.yml file is correctly configured for authentication. Check that the necessary IAM roles and permissions are set up for your Lambda functions.

    yaml
    iamRoleStatements:
      - Effect: Allow
        Action:
          - lambda:InvokeFunction
        Resource: '*'
  3. 3

    Clear Cache and Reinstall Node Modules

    Sometimes, cached modules can cause issues. Clear the npm cache and reinstall the node modules to ensure that all dependencies are correctly updated.

    bash
    npm cache clean --force && rm -rf node_modules && npm install
  4. 4

    Deploy the Application

    After upgrading the SDK and verifying the configuration, attempt to deploy your application again to see if the issue is resolved.

    bash
    serverless deploy --stage=staging
  5. 5

    Monitor Deployment Logs

    Check the deployment logs for any errors or warnings. If the authentication token error persists, review the logs for additional context or errors.

    bash
    serverless logs --function yourFunctionName --stage=staging

Validation

Confirm that the deployment completes successfully without the 'Request is missing Authentication Token' error. Additionally, check the logs to ensure that authentication is functioning as expected.
