Migrate your AWS Lambda functions to Node v22 ​

  • Make sure to upgrade aws-cdk-lib to v2.168.0 or higher first.
  • In your CDK code, change the runtime of your lambda to NODEJS_22_X.

Changed entry points of @backpack/aws-lambda ​

All REST-related utilities in @backpack/aws-lambda have been moved to @backpack/aws-lambda/rest. This means you have to update all your existing imports.
