Unable to get stacktraces for React/Typescript app

I am able to see issues on my Sentry dashboard, but they are not coming with stacktraces which makes it hard to debug issues. I am using webpack to automatically upload my sourcemaps and it appears to be working since I can see main.js and main.js.map in my releases artifacts tab (see picture).

My tsconfig.json looks like:

{
  "compilerOptions": {
    "outDir": "./dist/",
    "sourceMap": true,
    "noImplicitAny": true,
    "module": "commonjs",
    "target": "es6",
    "jsx": "react",
    "esModuleInterop": true,
    "allowJs": true,
    "inlineSources": true,
    "sourceRoot": "/"
  }
}

Likewise, my webpack.config.js looks like:

const SentryWebpackPlugin = require("@sentry/webpack-plugin");
module.exports = {
    devtool: "source-map",
    module: {
        rules: [
            {
                test: /\.ts$/,
                exclude: /node_modules/,
                use: {
                    loader: "ts-loader",
                }
            },
            {
                test: /\.tsx$/,
                exclude: /node_modules/,
                use: {
                    loader: "ts-loader",
                }
            },
            {
                enforce: "pre",
                test: /\.js$/,
                loader: "source-map-loader"
            },
            {
                test: /\.css$/i,
                use: ["style-loader", "css-loader"]
            },
        ]
    },
    resolve: {
        extensions: [".js", ".jsx", ".ts", ".tsx"]
    },
    plugins: [
        new SentryWebpackPlugin({
            include: ".",
            ignoreFile: ".sentrycliignore",
            ignore: ["node_modules", "webpack.config.js"],
            configFile: "sentry.properties"
        })
    ]
};

I’m using:

@sentry/webpack-plugin”: “^1.10.0”,
“source-map-loader”: “^0.2.4”,
“ts-loader”: “^6.2.1”,
“typescript”: “^3.7.5”,
“webpack”: “^4.41.5”,
“webpack-cli”: “^3.3.10”
@sentry/browser”: “^5.12.4”,

I’ve also noticed that the getting started guide seems to think I’ve not uploaded my source maps…
