Permission denied for gm binaries installed within AWS Lambda

[basimhennawi]

I'm using GraphicsMagick in my Lambda function (NodeJs 8.10) , for that I need to install both:

• the NodeJs library for it gm (latest 1.23.1) [That's fine!]
• and the GM binaries

To get the gm binaries on the Lambda, after some googling/stackingoverflow, get to create this github gist that states what I did briefly as follow:

• Create EC2 instance with Amazon Linux AMI that matches AWS Lambda's runtime.
• Install the gm there, tar it, copy it to my lambda, zipped it, packaged it, and deployed it.

Now the problem is that I got "Stream yields empty buffer" error whenever I used and manipulating method from gm, for that needed to check if my installed binaries there is correct, so added the following in my lambda handler function:

const exec = require('child_process').exec;
exec("gm -help", console.log)

And got the following "Permission denied" error as shown below:

Any clue? Thanks in advance!
