I am using "wrangler pages dev" for

I am using "wrangler pages dev" for building a simple Pages site (static html). I am getting errors from my browser due to the css file being served back with Content-Type: text/html instead of text/css. I see a few similar issues from 1-2 years ago, but not many, and no fixes. I also don't think I've had this issue with previous Pages developments. Any suggestions?
