Debugging Compound Templates
If you run a Compound Template and it fails to execute successfully, or if it executes successfully but does not produce the output you expect, you will need to debug the template. Template Builder contains a number of debugging functions and visual elements for debugging Compound Templates.
Note that debugging in Template Builder is asynchronous; you can step through the various parts of the Compound Template after it has run and examine the state of each Template Building Block as it was when it finished running.
