[chef-dev] Knife exec changes from chef 10 to 11?

[Mike < >]

I've been using a command similar to this for a while in chef 10, but now in chef 11 it no longer works:

knife exec -E'nodes.find(:name => "testnode.here.com") {|n| puts n.sudo.additional_sudoers(["blah","blah","blah",]);n.save'}

Is there a new way to set attributes from knife exec?  I had a script that I would use to create this command and its not working for me anymore.  Any suggestions?

Error message:

ERROR: knife encountered an unexpected error

This may be a bug in the 'exec' knife command or plugin

Please collect the output of this command with the `-VV` option before filing a bug report.

Exception: NoMethodError: Undefined node attribute or method `additional_sudoers' on `node'

:~/chefsy01exdu$ 

I am sure the attribute exists:

knife node show testnode.here.com -a sudo

testnode.here.com:

  sudo:

    additional_sudoers:

    sudoers:

Thanks in advance

Mike
