Test Kitchen Returns [no implicit conversion of nil into String]

Good Morning,

I am attempting to run through the Chef Learning tracks and stuck at creating an AWS EC2 Windows instance with Test Kitchen. The error received is below and Kitchen fails at this exact same spot every time. Debug log files are available if needed. Appreciate anyone’s thoughts on that matter and thank you so much!!

   Waited 0/600s for instance <i-0a8ff8aaef2652770> to fetch windows admin password.

Please see .kitchen/logs/kitchen.log for more details
Also try running kitchen diagnose --all for configuration

A gist of the .kitchen.yml you have, the debug logs, and a link to the specific page/module you are on would be great. Even better come join us Chef Community Slack in the #test-kitchen channel and we can try to troubleshoot this in realtime.


When I’ve run into this it was because I hadn’t configured my aws ssh key that allows me to pull the Windows password. This goes under transport and adding that as well as increasing the retries usually fixes it for me.

@cheeseplus, the information requested is below! Let me know if any issues accessing the GIST URL and thank you very much.

@dragon788, I created a new AWS Key Pair and generated a new Access Key ID for the IAM User and set those up accordingly on the Chef Workstation but still no go. Also attempted to increase the SSH Connection Retries as well. Thank you very much too!

Looks like the transport section is not properly aligned and since YAML takes it’s spacing/tabbing very seriously it’s not happy. Below I’ve fixed the alignment so you can see:

  name: chef_zero
  log_level: debug

  name: inspec

  ssh_key: c:\users\admin\.aws\us-east.pem

  - name: windows-2012r2

Removing the spaces from the beginning of the Transport line did the trick… unbelievable.

Thank you so much for helping a grasshopper find his way!!
