Exception indicating that you tried to use a function that requires
substitutions to be resolved, but substitutions have not been resolved
(that is, resolve() was not called). This is always
a bug in either application code or the library; it's wrong to write a
handler for this exception because you should be able to fix the code to
avoid it by adding calls to resolve().
