Error when reusing Symfony web server SSL certificate

[WouterCypers]

Problem description

I enabled HTTPS by using the Symfony web server SSL certificate as mentioned in the encore docs. However, running yarn dev-server yields the following error:

Running webpack-dev-server ...

<i> [webpack-dev-server] Generating SSL certificate...
<i> [webpack-dev-server] SSL certificate: /Users/woutercypers/Code/test-project/node_modules/.cache/webpack-dev-server/server.pem

It appears that this doesn't happen on older versions of Node. I tried Node the following node versions:

• v14.21.3 - works
• v16.20.0 - works
• v18.14.0 - fails
• v18.16.0 - fails

Used versions

• PHP: 8.0.28
• Node: v18.16.0
• Symfony CLI: 5.5.6
• symfony/webpack-encore-bundle: v1.17.1
• webpack-cli: 4.10.0

Steps to reproduce

1. Make sure to use Node v18
2. Add the following to your webpack.config.js

const path = require("path");

Encore
    .configureDevServerOptions(options => {
        options.server = {
            type: 'https',
            options: {
                pfx: path.join(process.env.HOME, '.symfony5/certs/default.p12'),
            }
        }
    })

3. Run yarn dev-server

Any help would be appreciated!
