问题 I am trying to take screenshots with puppeteer on aws lambda and upload the screenshot to a s3 bucket. However, the s3.putObject method doesn't seem to be working. On the lambda console, I got both the "uploading screenshot 's3://${s3bucket}/${filename}'" and "uploading completed" message but not the "inside callback" message.
