CodeWhisperer server broken for NPM Workspaces: Cannot set properties of null (setting 'dev')

[andredcoliveira]

Describe the bug

Installing @aws/lsp-codewhisperer in an NPM workspace fails with an error:

npm error Cannot set properties of null (setting 'dev')

To reproduce

You can use the following script:

#!/bin/bash

set -euxo pipefail

TMP_DIR=tmp_$RANDOM

mkdir $TMP_DIR
cd $TMP_DIR
npm init -y
npm init -y -w packages/a
npm install -w packages/a @aws/lsp-codewhisperer@0.0.6

Expected behavior

The installation should succeed.

Your Environment

• OS: Tried in Amazon Linux 2 and also in macOS Sonoma 14.5
• NPM: 10.7.0

Additional context

This affects versions 0.0.5 and 0.0.6. Version 0.0.4 still works.

NPM Debug log is attached: 2024-06-26T15_06_43_763Z-debug-0.log

Importing the module afterwards also seems broken, which is kind of expected since the installation failed:

Tested v0.0.9 with the script below and it seems to work now:

#!/bin/bash

set -euxo pipefail

TMP_DIR=tmp_$RANDOM

mkdir $TMP_DIR
cd $TMP_DIR
npm init -y
npm init -y -w packages/a
npm install -w packages/a @aws/lsp-codewhisperer@0.0.9

Thanks!
