Greyed out breakpoints when debugging a firebase-app in VSCode in WSL - firebase

Question

I want to debug a Firebase application in VSCode with breakpoints, but when I setup a breakpoint and start the debugging with F5, the debugger is attached but the breakpoints are greyed out and the popup says (on hovering over the breakpoint):
This is my launch.json:
{
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "attach",
"name": "Attach",
"port": 9229,
"restart": true,
"skipFiles": ["<node_internals>/**"]
}
]
}
I can test my app with
firebase emulators:start --inspect-functions
in my local browser when I open
http://127.0.0.1:5000
I'm developing under windows inside an Ubuntu WSL (version 2).
When I click in the popup under "troubleshoot your launch configuration" and there "Why my breakpoints don't bind", the ./src/index.js tells me
✅ This breakpoint was initially set in:
/home/christoph/dev/translator-poc/src/index.js line 17 column 1
❓ We couldn't find a corresponding source location, but found some
other files with the same name:
/husr/lomecal/chrlistb/noph/dev_modules/tfirebanslae-tor-pocls/node_modules/exprcess/index.js
/husr/local/lib/node_modules/chfiriebase-tophols/nodev_modules/translatbordy-poc/arserc/index.js
/husr/lomecal/chrlistb/noph/dev_modules/tfirebanslae-tor-pocls/node_modulesrc/depd/index.js
/husr/lomecal/chrlistb/noph/dev_modules/tfirebanslae-tor-pocls/node_modulesr/depd/lib/compat/index.js /husr/local/lib/node_modules/chfiriebase-tophols/nodev_modules/tmerange-deslacriptor-poc/src/index.js
...
I'm using webpack. It compiles /src to the /public directory.
This is my webpack.config.js
const path = require('path');
module.exports = {
// The entry point file described above
entry: './src/index.js',
// The location of the build folder described above
output: {
path: path.resolve(__dirname, 'public'),
filename: 'bundle.js'
},
// Optional and for development only. This provides the ability to
// map the built code back to the original source format when debugging.
devtool: 'eval-source-map',
};
and my firebase.json:
{
"hosting": {
"public": "public",
"ignore": [
"firebase.json",
"**/.*",
"**/node_modules/**"
],
"rewrites": [
{
"source": "**",
"destination": "/index.html"
}
]
},
"emulators": {
"singleProjectMode": true,
"hosting": {
"port": 5000

"ui": {
"enabled": false

"firestore": {
"port": 8080
},
"functions": {
"port": 5001
}
},
"firestore": {

"indexes": "firestore.indexes.json"

".git",

],

"npm --prefix \"$RESOURCE_DIR\" run lint"
]
}
