CI Node version matrix not applied

[annaerdi]

CI Node version matrix not applied – using default Node 20.x (Ubuntu) and 18.x (Windows) for all 6 runs.

• Operating system and version: GitHub-hosted runners (ubuntu-latest, windows-latest)
• Browser and version: N/A (CI-related)

Bug description:

The GitHub Actions workflow .github/workflows/npm.yml defines a matrix to test across Node versions 16.x, 17.x, and 18.x, but the setup-node step references env.node-version, which is not connected to the matrix.

As a result, the matrix is not being used, and the jobs are falling back to the default Node versions provided by GitHub runners.

For example:
✅ build (ubuntu-latest, 17.x) — succeeded but actually ran:

node: v20.19.0
npm: 10.8.2

Suggested fix:

In the workflow file, replace node-version: ${{ env.node-version }} with node-version: ${{ matrix.node-version }}, however, this will likely cause the workflow to fail.
