Is there currently a known issue with arktype + trpc compatibility?

This is with latest RC.12

TypeError: Cannot read properties of undefined (reading 'traverse')
    at assert (/node_modules/@ark/schema/out/roots/root.js:80:29)
    at inputMiddleware (/node_modules/@trpc/server/dist/index.mjs:278:33)

This occurs when I do .input(type(anything).assert). If I do something such as .input((i) => type(anything).assert(i)), it works fine. How on earth is it ending up with this being undefined when it is run this way?

aha, you can no longer pass an arktype assert around the way trpc docs show

let test = type("string[]")
let testFn = (inputFn) => inputFn({})
testFn(test.assert)

let test = type("string[]")
let testFn = (inputFn) => inputFn({})
testFn(test.assert)
