Non-text file upload fails

[hiucimon]

I am working on a program that needs a binary file to be sent to it, so I downloaded Wasabi, and created this little test program. No, not very clean and yes I know I am just printing null but it is just to see if I am getting to the print. If I supply a txt file, things are fine, as is the two other forms, but any binary file I select results in:

[nioEventLoopGroup-3-4] INFO org.wasabifx.wasabi.interceptors.LoggingInterceptor - [GET] - /bad-request

With the following program:

import org.wasabifx.wasabi.app.AppServer

fun main(args : Array) {
println("Started")
var server = AppServer()
server.get("/testget",{
println(request.bodyParams["filename"])
})
server.post("/testpost",{
println(request.bodyParams["filename"])
})

server.post("/upload",{
    println(request.bodyParams["filename"])
})
server.start()

}

And the following HTML:
