Webpack alliases work in browser, but not in node - node.js

Question

To start off, this is my first post on stackoverflow so I hope I'm doing it right...
So my Webpack alliases work in browser, but not in node
I have a package (let's call it Services) with a subfolder dev and another project (let's call it MobX) which uses Services. In Mobx, I have a webpack configuration which is supposed, in development mode, change the paths of Services to have access to the subfolder dev instead.
Here's a sample of the code :
const devConfig = {
...commonConfig,
mode: "development",
devtool: "cheap-module-source-map",
entry: "./src/lib/index.ts",
output: {
path: outputDir,
library: name,
libraryTarget: "umd",
globalObject: "this",
},
optimization: {
minimize: false,
},
plugins: [...commonConfig.plugins, forkTsCheckerWebpackPlugin],
resolve: {
...commonConfig.resolve,
alias: {
"#intuition/services-apis$": "#intuition/services-apis/dev",
},
},
};
const devConfigNode = {
...devConfig,
target: ["node"],
name: "node",
output: {
...devConfig.output,
filename: splitChunks ? "[name].[contenthash].node.js" : "index.node.js",
},
};
const devConfigBrowser = {
...devConfig,
target: ["web", "es5"],
name: "browser",
output: {
...devConfig.output,
filename: splitChunks ? "[name].[contenthash].browser.js" : "index.browser.js",
},
};
I don't understand why, in node, it doesn't go into #intuition/services-apis/dev. In works fine in browser but no matter what I do, in node, it doesn't work. I have been at this day for days now and I can't seem to figure it out.
If my explanation wasn't clear enough and needs more details, please do not hesitate to ask any question.
