Custom not fingerprinted

I have the following code in ember-cli-build.js:

outputPaths: { app: { html: 'Default.aspx' } }

(we are using .net as a backend and we need the generated app file to be Default.aspx)

Everything works fine when building for development environment. However, when I try to build to production with:

ember build --environment=production

the <link/> and <script/> tags for .css and .js files in Default.aspx do not get fingerprinted, but the actual files are generated with the fingerprint added to them. This causes the application not to load.

Did anyone have similar issue? Any thoughts on what could be causing this? If I have set to any .html file, the fingerprints are added correctly.
