When debugging queries on a MarkLogic database that imports modules stored in the
database, the recommended steps for placing a breakpoint in a module are as
follows:
-
Start the debugging session with the action
Debug Scenario
from the Transformation toolbar or the 
XQuery Debugger
toolbar button.
-
Click
Step
into repeatedly until reaching the desired module.
- Add the module to the current project for easy access.
- Set breakpoints in the module as needed.
- Continue debugging the query.
When starting a new debugging session, make sure that the modules that you will debug
are already opened in the editor. This is necessary so that the breakpoints in the modules
will be considered. Also, make sure that there are no other opened modules that are not
involved in the current debugging session.
