Jimp: Jimp writes an empty png file after modification

[master-of-null]

Expected Behavior

I'm running this process on AWS Lambda. I'm expecting the file to be modified and then written

Current Behavior

The file that is being written is a 0 Byte empty file .png file. I put the file before the mod in s3, it's as expected. I put it in s3 again after editing it and it puts a 0B file in the bucket

It does work sometimes, but 20% of the time it writes an actual image

Failure Information (for bugs)

I'm not getting an error, it's just writing an empty file.

Steps to Reproduce

    const image = await Jimp.read(path)
    await image.invert().contrast(0.7).write(path) 

Context

Node v8.10 on AWS Lambda

• Jimp Version: 0.6.0
• Operating System: Amazon Linux
• Node version: 8.10

Failure Logs

None

I have never used AWS myself so idk how to easily make a reproduction of this. Could you provide an example repo with AWS setup instructions?
