Is there any limitation for having nested List of Structures in REST API Integration
Like below

In above image each AnalysisNo object within AnalysisNo array have inner array called DataPoints,
when I'm having the inner array I'm getting the below error, but when I tried to execute that function in PLSQL its executed without any error

without that Inner array it works fine as below

Is there a limitation like this or any workaround for this?
Below are the projection function and the structures
