So you stumbled across some old code. The add crawl page is deprecated and is about to be removed. Adding crawls should be done from the project page only.

We still have some legacy code that we are trying to get rid of (probably this week sometime).

How did you access the add_crawl page? Through the sidebar?

[antrromet]

Yes. When you click on Crawls from the side bar, then it gives you the list of all crawls. And there at the bottom right, there is a button Add Crawl that gives this problem.
The url for the same is http://localhost:8000/projects/sample/crawls/

Thanks. I'll fix this issue in a PR soon. For now i'm going to temporarily disable that page.

All crawls should be added from the project page.
