Hello,
First off you may note you are using v1.16.3. Which would indicate you haven't followed the setup. Other steps may have been skipped as well.
Also re-read step nine, which says to edit the first.yaml file and remove the various lines which are throwing errors when you try the replace.

Hello, I am getting this same error. Here is my first.yaml. The instructions say that the spec section is around line 31. However for me it was around line 117. I am assuming that I'm not supposed to change what is in the metadata section.

just deleting the original deployment and re-creating seems to work though.
