Page Editor does not work ../API/identity/user/{{userId}}

I have installed Bonita Community Edition Version : 2023.2 Version id : u0 Build id : 9.0.0

In UI Designer in PAGE Editor the API call does not work ../API/identity/user/{{userId}} in userId is a value stored in BDM, exactly this is what I am referencing ../API/identity/user /{{complains_selected.agentId}}, complains_select It is the variable that is automatically created when you select my model from the BDM, agentId is the user who performs a human activity, but I need to display the first and last name and not just the userId.

In FORM Editor it works correctly so I can know what the first and last name of the userId.

Please help.
