layout: close("{id}") - no such window.

What happened

layout.close(id) was called with an id the layout does not hold. Nothing was closed and the call returned false. The usual causes are a typo, an id that was never added, and calling close twice for the same window - the second call arrives after the window has already gone.

The fix

Check the id against layout.windows(); ids are compared as strings, so a numeric id and its string form are the same window but a trailing space is not. Guard repeat calls on the window:closed event rather than on your own bookkeeping.
