The issue was that I had layout: layout in frontmatter instead of layout: layout.njk. I'm guessing the extension is now required in 2.0. Is there a changelog / breaking change list I can contribute this to (if I'm understanding correctly)?

[zachleat]

Restoring this feature in #2708, shipping with v2.0.0-canary.21.

[mehulkar]

@zachleat fwiw, I’m on board with requiring extensions! Just didn’t know where to check to see the “breaking” changes so I could debug the error. One simple fix in my case would be to wrap the missing layout name in quotes in the error message. Would have made it more obvious that 11ty is looking for something I’ve named.

Ah yeah, no worries! We just got 3 issues on this specifically recently 😅 so I’m gonna slow walk this migration
