Why is Jinja2 urlize filter not working with GAE flask app?

[BLONDEV INC]

When I run my flask app locally, the Jinja2 urlize filter works beautifully, converting the URL from text to hyperlink.  

  

Here is how I am implementing (beautifully simple) in the template:  

When, however, I deploy the app via GAE (3.7, standard environment), the URL is just text on the page, without the hyperlink. 

  

What is going on here? How do I remedy this?

You probably did not register this filter; you have to register the filter using a statement similar to: jinja_env.filters['variable_name_here'] = identifier.
