Failed to convert x265 using ffmpeg scale_npp

I'm trying on Win10 (through MinGW64) to convert (mixing mode) from x265 file (by CPU) to x264 (by GPU - NVidia) resizing the output using scale_npp.

What means last 5 rows on this logs?
tnx!

    $ ffmpeg -i /i/_wip/xxxxxxxxxxxxxxx.MULTI.1080p.BDRip.x265.10bit.AAC.2.0.Subs.Fr.Eng.mkv -c:v h264_nvenc -an -vf "fade,hwupload_cuda,scale_npp=304:120" -pix_fmt yuv420p -preset fast /i/_wip/test1_output_h264.mp4
