unknown_field

Summary

unknown field `{1}` on `{0}`

Details

When this fires

A .field lookup on a struct hit a name the type doesn't have. Unlike missing_key (maps), this is structural: the schema of the value simply doesn't expose that field. Raised by the renderer when field_by_name returns None.

What to check

Struct fields are case-sensitive. The field may have been renamed or removed in a recent nanook update, check the trigger context reference in @/docs/nanook-templates.md.
