Issue with "Export List" Action on Custom Tree Table – No Data Exported

[SK_8706763]

I am using Windchill PDMLink Release 12.1 and Datecode with CPS 12.1.0.1

When using a custom TreeBuilder to populate a tree table component with data from a JSON file, the OOTB Export_file action only exports the header values and not the data. The same data is correctly displayed on the UI but not populated in the exported Excel sheet. The custom TreeBuilder is mapping JSON attributes to a bean file, and the tree table is displaying the values as expected. However, the exported Excel sheet shows only headers without any data rows.

Steps to Reproduce:

Populate a tree table using a custom TreeBuilder with data from a JSON file.
Verify that the data is displayed on the tree table UI.
Use the OOTB Export_file action to export the tree table to Excel.
Observe that the Excel sheet shows only the headers without data.

Here are the errors that I faced
