# Symptoms
This code produces a big ugly confusing error in the frontend, see #7340.
# Root cause
I added a new test case, with an unknown type. In `ast.snap` under `body[0].declaration.init.ty` there two different `type` fields in the AST node for the type's name, and they have conflicting values Primitive and Identifier.

# Solution
Change the `enum PrimitiveType` variant from `Named(Node<Identifier>)` to `Named { name: Node<Identifier> }` so that the fields nest differently.
Now the error correctly points out to the user that the type `NotARealType` can't be found. Much better error message that shows the user the problem.
# Alternative solutions
Stop the duplicated JSON fields altogether. I tried this previously in https://github.com/KittyCAD/modeling-app/pull/4369 but it was very involved, and I didn't think it was worth it. Maybe I should reopen that PR and solve this properly.
