"Internal server error" for full-fit-in resize request

[onassar]

Running into an issue with the full-fit-in resize request.
Here is the S3 object:
http://s3-us-west-2.amazonaws.com/app.getstencil.com/asstdb633ecc

And when I request the following, I get an "Internal server error":
https://d3mnhso4gv2l51.cloudfront.net/full-fit-in/3200x3750/asstdb633ecc

However, when I request a slightly smaller resolution of the image, it works fine:
https://d3mnhso4gv2l51.cloudfront.net/full-fit-in/3200x3200/asstdb633ecc

My first thought was that the image was taking too long to resize, but similar dimensions take only a few seconds.
My second thought was that it was beyond the acceptable resolution, but it seems the maximum resolution for this solution is 70mb.

Any thoughts?

Closing this issue, as I've found out by investigating my CloudWatch logs that it's related to the output being larger than the maximum allowed through Lambda (namely, 6mb, which is documented here: https://docs.aws.amazon.com/lambda/latest/dg/limits.html)

That makes this issue a duplicate of: #35
