undefined local variable or method `chef_version', possible package version issues

[nicholasserra]

Hello, hoping someone may be able to give me some direction on an error i'm seeing. I'm assuming i'm probably out of date or running incompatible versions to be getting this error during bootstrap.

Running:
Ruby 2.2.2
chef (12.15.19, 12.5.1)
knife-ec2 (0.13.0)

The short error is

Exception: NameError: undefined local variable or method `chef_version' for #<Chef::Knife::Core::BootstrapContext:0x007f9f3e7bf248>

And with verbose output it is

(erubis):23:in `block in evaluate': undefined local variable or method `chef_version' for #<Chef::Knife::Core::BootstrapContext:0x007fbcceab5440> (NameError)

This ended up being an invalid variable in the bootstrap template.
