Error: Conflict: Multiple chunks emit assets to the same filename ssr-bundle.js

Hi, I have encountered this problem when I was trying to create multiple html files with multiple entries.

Error: Child compilation failed:
  Error: Conflict: Multiple chunks emit assets to the same filename ssr-bundle.js (chunks 1 and 2  )

//webpack config
config.entry = {
  a: './a.js',
  b: './b.js',
}

Object.keys(config.entry).map(i => {
  config.plugins.push(
    new HtmlWebpackPlugin({
      template: `!!prerender-loader?string!./template.html`,
      filename: `${i}.html`,
      hash: false,
      chunks: [i],
    }),
  );
});

I have tried below but doesnt make any difference.

template: `!!prerender-loader?${JSON.stringify({ string: true, params: { url: `/${i}/` } })}!./template.html`

        "html-webpack-plugin": "^4.0.0-alpha.2",
        "prerender-loader": "^1.2.0",
        "webpack": "^4.29.3",
        "webpack-assets-manifest": "^2.0.0",
        "webpack-cli": "^3.1.1",
        "webpack-dev-server": "^3.1.14"

node v11.9.0.

Any ideas?

@edwardfhsiao alright, I figured out the issue with the demo you linked above: it’s a duplicate of #25, and the solution I posted there a couple hours ago works here too:

Object.keys(config.entry).map(i => {
  config.plugins.push(
    new HtmlWebpackPlugin({
-     template: `!!prerender-loader?string!${PATH.HTML_PATH}/template.html`,
+     template: `!!prerender-loader?string&entry=${config.entry[i]}!${PATH.HTML_PATH}/template.html`,
      // etc
    }),
  );
});

@northamerican <%= htmlWebpackPlugin.options.title %>just comes from

 new HtmlWebpackPlugin({
      ...
      title: `${i}`,

It is a format of HtmlWebpackPlugin, which does not really matter in this case.

As for the multiple entry issues, I guess still needs @developit 's help.
