[rlerch]

Hello All,

A get request with a malformed query string causes a 500 error with the message
invalid hex byte 's%' at index 3 of '/?%s%'

Steps to reproduce,

• Start a ktor server.
• Navigate to http://localhost:2000/?%s%
• Server than returns 500

Expected Behavior

Server returns 400 Bad Request
