StreamFile Crash

[dnKaratzas]

I try to stream a file stored local on my machine. I am launching VLC given the server url, the player starts playing the file correctly but If I will change the position of the movie I got that crash.

NIOHTTP1/HTTPServerPipelineHandler.swift:115: Fatal error: Unexpectedly received a response in state sentCloseOutput

My route:

app.get { req async in
        let fileUrl = URL(fileURLWithPath: "....mp4")

        let res = req.fileio.streamFile(at: fileUrl.path)
        return res
}

@dnKaratzas what version of SwiftNIO do you have since the crash is occurring there?

[dnKaratzas]

@0xTim 2.52.0

[0xTim]

@dnKaratzas tracking here apple/swift-nio#2420

[dnKaratzas]

@0xTim can confirm that SwiftNIO 2.51.1 causing that crash. Used SwiftNIO 2.51.0 and the crash don't occur

[0xTim]

@dnKaratzas just to confirm this isn't crashing anymore if you update your dependencies?
