Google Not Detecting Structured Data

Hi,

After marking several of my articles as rich snippets (article rich snippet), I tested it out with Google’s structured data testing tool:

https://developers.google.com/structured-data/testing-tool/

For example, I tested this page: https://www.netflixdnscodes.com/guides/how-to-get-american-netflix-in-canada/

But it says no structured data is present.

Am I doing something wrong?
