Can't rezie any pngs

png’s dont resize. jpgs work just fine.

This bit of code sends the resized images to S3 for context

function writeObject(data, width, newFilePath, callback) {
    return Sharp(data.Body)
      .resize(width)
      .toFormat('png')
      .toBuffer()
      .then(buffer => S3.putObject({
          Body: buffer,
          Bucket: BUCKET,
          ContentType: 'image/png',
          Key: newFilePath,
        }).promise()
      )
      .then(() => callback(null, {
        statusCode: '301',
        headers: {'location': `${URL}/${newFilePath}`},
        body: '',
      })
    )
}

The output is the original file in original size. I have tried 5 or 6 png files, both from google images and ones I made. I don’t think its a png file issue but I’m happy to link a test image here if needed. I’m also confused why its not throwing an error?

@lovell I have not, but I need to get this this soon, probably after the new year. Thanks for following up

@lovell sorry it took so longer to circle back to this, too many projects not enough time. I went and broke down the code into simple tests and uhm… it was working. Turns out the lambda method I wrote had a bug, not in the writeObject method, but in the wrapper method that recursively called it with various “approved” file extension types that it would restrict on and guess at while grabbing objects from S3. I was only passing the width param the very first time, but not the recursive case and so JPEG was the first extension in my array, PNG was not… e.g. PNG never got the width param… my fault. Long story short, this is not a bug, please close 😃
