[racket] raco exe: unknown module

Could submodules be causing it?
try.rkt:
#lang typed/racket/base
(provide x)
(define x : Integer 1)
(module* test racket/base
  (require (submod ".."))
  x)
Gives this error:
. . Racket v6.1.1.8/collects/racket/private/reqprov.rkt:79:13: syntax-local-module-exports: unknown module
  module name: #<resolved-module-path:(submod 'try #%contract-defs)>
