Steps to Reproduce

Create a strategy rule and for testing reference a data page with a parameter such as D_Customer[myCustomer]

Root Cause

The syntax used is only accepted when Expression Builder is enabled, which is not the case in Strategy rule.
This is extracted from the documentation:
Presume you have a data page named D_Customer, with parameters CustID and DetailLevel that let you specify the customer and the level of detail the instance of the data page holds, reference the data page using this syntax:
D_Customer[CustID:myCustomer, DetailLevel:Full] 
If the data page requires only a single parameter, you can provide the parameter without specifying the parameter name. If D_Customer has a single parameter, CustID, use this syntax:
Note: The system accepts either of the above syntaxes to reference a data page only in a field where the Expression Builder is enabled. For example, you cannot use the syntax in the findPage() PublicAPI method.


Use this alternative approach:


Create a page property and reference in strategy (in the example below "xavpage"):



Define the page property (in this example "xavpage")  to be populated via Declare page and via the parameters desired.
