Ch4 Node.js playbook; Fatal error "Failed to get information on remote file ... not a directory" when run task "Copy example Node.js app to server

RockyLinux 8.6
Ansible core 2.12.2

When that step is reached using the YAML from the book, ansible throws the following:

`fatal: [anstarget3]: FAILED! => {"msg": "Failed to get information on remote file (/usr/local/opt/node/app/app.js): Not a directory"}`

It looks like this is down to passing in the var `node_apps_location: /usr/local/opt/node`

leaves us with no "app" directory into which files can be copied.

Changing line 32 from

`file: "path={{ node_apps_location }} state=directory"`

to

`file: "path={{ node_apps_location }}/app state=directory"`

sets it up correctly and all files are copied over as expected.

Review the Chapter 4 Node.js playbook at line 32 and the task "Copy example Node.js app to server," focusing on how node_apps_location is used for the destination. Confirm the directory setup and copy behavior on the stated Ansible and Rocky Linux versions; done means the app directory exists and all files copy without the "Not a directory" error.
