cloud-assembly-schema: incompatible version of Node.js

[sakurai-ryo]

Describe the bug

Hi Team,

After this PR was merged, the aws-cdk-lib now uses the cloud-assembly-schema that was externally published.
#31064

Previously, >= 14.15.0 was specified in engines in package.json, but now >= 18.18.0 is specified and the compatible version was updated.

Before:

aws-cdk/packages/@aws-cdk/cloud-assembly-schema/package.json

Line 108 in 5f30aa5

"node": ">= 14.15.0"

Now:

  "engines": {
    "node": ">= 18.18.0"
  },

https://github.com/cdklabs/cloud-assembly-schema/blob/7468c327aa0b0ef46c4b971ac36278ef57fb2b8b/package.json#L81

This may cause errors when installing or updating aws-cdk-lib if you are using a version of Node.js lower than 18.18.0.
You can ignore Node.js version compatibility with the --ignore-engines option in yarn, but this is a something to avoid if at all possible.

Last Known Working CDK Version

v2.154.1

Expected Behavior

The installation and upgrade of aws-cdk-lib should work without errors or warnings.

Current Behavior

In the case of yarn, you will get the following error.
error @aws-cdk/cloud-assembly-schema@36.0.19: The engine "node" is incompatible with this module. Expected version ">= 18.18.0". Got "18.17.0"

Reproduction Steps

Using a version of Node.js lower than 18.18.0, execute the following command.

$ yarn add aws-cdk-lib@2.154.1

Possible Solution

If there is no obvious reason to require a version higher than 18.18.0, specify >= 14.15.0 for engins, as with aws-cdk-lib.

Reproducible.

Tested on OSX:

• Install node using command brew install node@16.
  • Add node to PATH using command echo 'export PATH="/opt/homebrew/opt/node@16/bin:$PATH"' >> ~/.zshrc.
• In a CDK project, try executing yarn add aws-cdk-lib@2.154.1
