Error: java.lang.NullPointerException; Line#: 6; Column#: 1784[java.lang.NullPointerException] in the Test_DataMapping.
In the data mapper, you are loading two schemas at the target, one is an Adv. Positional schema and second one is a context schema .
Adeptia only allows loading a single context schema at the source end or at the target end in the data mapper. You can create another mapping for saving the values in the context variables or set context variables globally in the data mapper. (Please refer “Transforming Data > Using Mapping Functions > Using Set-Context Function” in developer guide)
