I am getting an error "could not execute phantomjs". This is on my ec2 server. Here is the listing:

Please tell me what to fix?

I don't see a phantomjs execution file. I was thinking that it is Handler.php that needs to be changed? Am I wrong? Where would phantomjs be located?

Still there. richb201@richb201-XPS-13-9370:/opt/docker-substantiator2/app/vendor/koolreport/export/bin$ ls -l total 66344 -rwxrwxrwx 1 richb201 richb201 67932064 Jan 25 2016 phantomjs
