Describe the bug

The error seems internal to nu . At some point, I also got a Broken pipe error, but I did not manage to reproduce the issue.

> update value (get value)                                                                                               
Error: nu::shell::io_error

  × I/O error
  help: can't follow stream paths

How to reproduce

Just run the snippet given above.

Expected behavior

A better error message. Probably the correct syntax is to use curly brackets, and the error message could make such a suggestion.
