Could you upgrade zod version?

[hirosaki217]

@hookform/resolvers and react-hook-form not compatible with zod version of ai sdk
when i upgrade ai sdk to v5 it fail typecheck everywhere use resolver schema. every schema use preprocess not understand type, and default is unknown
zod version im using is 4.0.14
ex:

const preprocessString = (arg: unknown) => {
  if (arg === null || arg === undefined || arg === '') {
    return undefined
  }
  return String(arg)
}

export const NonEmptyStringSchema = z.preprocess(
  preprocessString,
  z.string().min(1)
)
