History api fallback does not handle `index.ejs`

[Svehla]

Hi,
First of all. Thanky you for your job! 🙂

I already spend few hours with unsuccessful configuring of historyApiFallback

So I set in union.config.js:

devServer: {
  historyApiFallback: true,
},

It look that it works well, but problem is that history-api-fallback serve index.html as default and not index.ejs

so if i rename index.ejs to index.html and history-api-fallback starts to work only for nested path (like localhost:3300/a/b) because root still goes to index.ejs

so I added to union.config.js:

templateFilename: 'index.html',

Now it looks like that it works but if I go to:
localhost:3300/something/id/something

it does not render and load any wigets. (maybe some bad relative paths of <script src=?)

So It looks like that for local developing of react I don't need .ejs but some dependency in index.(html/ejs) are not valid if I have nested URL like localhost:3300/something/id/something

I can't find real purpose of the nested URL problems.

Thx for help 🙏
