Pressing Tab after selecting a whole file causes textDocument/documentSymbol error #111
Description
Steps to reproduce
- Save the following content into a file (must be saved, can't use an unsaved buffer)
- Select all, press Tab
#lang racket
(provide USER LOG)
(define USER (make-parameter "nobody"))
(define (LOG . as)
(with-output-to-file "log.txt" #:exists 'append
(lambda () (printf "~a: ~a\n" (USER) (apply format as)))))
Expected
All lines are indented, no error occurs.
Actual
All lines are indented, but for some reason the lang server also shows this error:
Caught exn in request "textDocument/documentSymbol"
rest: contract violation
expected: (and/c list? (not/c empty?))
given: #<void>

If you do the same in a unsaved buffer, this does not happen.
