After upgrading to 0.19 I am getting ` Test call 'containing' failed`, even if I drop all these tests from the template:

```auto
Error: Failed to serve the site
Error: Failed to render section '/home/charlie/src/halve-z/content/_index.md'
Error: Reason: Failed to render 'index.html' (error happened in a parent template)
Error: Reason: Test call 'containing' failed
Error: Reason: Tester `containing` was called on an undefined variable

```

CI: [fix(config): set `generate_feeds` · charlesrocket/halve-z@6696f1f · GitHub](https://github.com/charlesrocket/halve-z/actions/runs/9930084955/job/27428413268)

Is there a way to get more info on the error?

In abridge I was getting a similar error using the **containing** terra function, it was because the feeds had changed:

just grep your site for **containing** and if you use that function for feeds, then also grep for **feed**
