Modified Variables Propagation in GET Request Captured in Try Catch

The workflow sends a GET request inside of a Try & Catch construction. The flow variable totalItems containing the total number of books available on Google Books for all search terms is created inside the Try & Catch construction. For the case when the GET Request fails, a Custom message flow variable is created in the alternative branch.
With propagating the variables option, either totalItems or the Custom message flow variable is exported by the Try&Catch construction, depending on which branch was active.
