This often happens when your template references an asset, in this
case style.css, that doesn't exist (you should avoid using relative
paths on pages that have an activation context).
What happens is that the page renders, the client asks the server for
style.css relative the page's base URL ... that doesn't match a file
in your context, and the URL looks like a page render request with an
activation context that looks like "style.css" ... and that can't be
converted to a long.
Again, the solution is to avoid relative paths. Strip out style.css
from your page or layout template, use the @IncludeStylesheet
annotation instead of directly-code HTML.
