"manage_addFolder" wants to have a string argument (that is
what "read-only character buffer" usually means).
Instead, it get a "Python Method".

Explanation:
  "id" is often a method returning a string, not directly a string.
  Sometimes, i.e. for some classes, it is the string itself.

You may use "_['id']". This is equivalent to "id()", if
"id" is callable and to "id", if it is not.
