Seeing issues of istanbul-instrument-loader, I changed my depencies just got blank file: image Here if my config: karam.conf.js, use 'coverage-istanbul' reporter

 webpack: {
        mode: 'development',
        devtool: "inline-source-map",
        module: {
            rules: [
                {
                    test: /\.ts?$/,
                    // 指定源码位置
                    include: [path.join(__dirname, 'src')],
                    use: [
                        {
                            loader: "coverage-istanbul-loader",
                        },
                        {
                            loader: 'ts-loader',
                        },
                    ],
                    exclude: /node_modules/,
                }
            ],
        },
        resolve: {
            extensions: ['.ts', '.js', '.json']
        },
    },

tsconfig.json

  },
  "exclude": [
    "node_modules",
    "test",
    "lib"
  ]
}

The coverage report is not correct too: image Since I only tested 3 functional files, the right one is (using instrument-loader): image
