Fiori Factsheet - TypeError - Cannot read property 'forEach' of null

Hello All,

Were implementing Factsheet (Customer, Customer Billing Document, Sales Order and Sales Quotation).

I was able to search but when trying to click the header it throws an error "Could not open app. Try again later".

Upon checking the error using Inspect it says "TypeError - Cannot read property 'forEach' of null".

Does anyone experience this kind of error? Any suggestion on how to check this further or how to resolve this issue?

Thanks in advance.
