CloudFront functions accessing full URL or # fragment identifier

Looks like the URL is pre-parsed into uri and querystring, but it leaves out location property or fragment identifier. We use vue.js and it creates URL's like domain.com/#/path/to/something/?optional=true and I want to conduct a check against the vue path. Is there a way to achieve this without proxying it through an actual server?

I've also attempted this with lambda@edge python snippet printing out event. Looks like it has the exactly the same behaviour if configured as viewer-request handler.
