cannot fetch features: VP8_STATUS_BITSTREAM_ERROR

[frops]

I'm trying to convert png to webp and getting error "cannot fetch features: VP8_STATUS_BITSTREAM_ERROR".

func (c *ConvertService) ConvertToWebp(file io.Reader, d entities.Dimensions) (image.Image, error) {
    img, err := webp.Decode(file, &decoder.Options{})

    if err != nil {
        return nil, err
    }

    return transform.Resize(img, d.Width, d.Height, transform.Linear), nil
}

OS: macOS Catalina, 10.15.7 Lib: webp 1.2.1 Go: 1.17

If I understand correctly, you try to open png file by webp decoder, right? if i'm right, firstly you have to open png file with png decoder and try encode result image.Image with webp encoder to create webp picture
