Caused by: com.pega.pegarules.pub.clipboard.WrongModeException: Property theTenantWrapper.PACshortcutPageGroup must be of a page or list mode for JSON mapping<CR> at com.pega.pegarules.integration.engine.internal.JSONMappingUtils.getOutboundJSONValue(JSONMappingUtils.java:261)<CR> ... 67 more<CR>]
Steps to Reproduce
- Create a REST service and include a page group property
- Map the response to the page group property
- Select the 'Use Fast Processing' feature
- Run the flow
Root Cause
In Pega 7.4, Fast Processing does not support page groups, value groups, and Java objects.
Resolution
Perform the following steps:
- Ensure to match the JSON property names and the clipboard property names
- Ensure to create the JSON tree structure such that it is similar to the clipboard tree structure
- Map the scalar arrays in JSON to the clipboard as page lists
- Map the multi-dimensional arrays into page lists with the same embedded property names
