Tree-sitter node type error when trying to set up font lock

[Jeremy Baxter]

Hi list,

I'm working on a tree-sitter-based major mode for D, and after setting
up font lock I receive the following error in the *Messages* buffer:

    Error during redisplay: (jit-lock-function 3193) signaled 
(treesit-query-error
    "Node type error at" 3 "[\"alias\" \"class\" ...] @font-lock-keyword-face"
    "Debug the query with `treesit-query-validate'")

A minimal sample of the source is attached but this vector in the
error is replaced with the contents of `d-ts--keywords' spliced into a
vector. Calling `treesit-query-validate' doesn't tell me anything new
either. Does anyone know what I'm doing wrong?

Thanks,
 ~Jeremy
