i want to assign the Processes.CaseLog_Transactions_process_QueryEntityData.out_ExcelRecords(0).Handler to a text box string type.

Hi @JomarieBancolo

This happens because App Studio is strict (typed) and Cloud Studio is flexible. In App Studio, Handler is not recognized as a direct field of that entity, so it throws an error.

Try accessing it like:
Processes…out_ExcelRecords(0)(“Handler”).ToString

Or check the exact field name in Data Service (it may be different).

Hi @JomarieBancolo

Since out_ExcelRecords(0)("Handler") is also failing, it likely means the field is not exposed as a direct property in the entity type returned to App Studio.

A few things to verify:

  • Check the exact schema/field name in Data Service or the process output.
  • Confirm out_ExcelRecords is really a DataTable/List and not a custom entity object.
  • Try inspecting the object using a temporary label or log to see available fields.
  • If this comes from an entity relationship/reference field, you may need to access a nested property instead of "Handler" directly.

Example:

Processes.out_ExcelRecords(0).Handler.DisplayName

or

Processes.out_ExcelRecords(0).Properties("Handler")

depending on the object type.

App Studio enforces strong typing, so the syntax depends on the exact structure of the returned entity.

App Studio is strict (typed), so you can’t use (“Handler”)
use below :
out_ExcelRecords(0).Handler
If this still fails, it means Handler is not in the output schema (even if visible in UI).
Check with IntelliSense (Ctrl+Space) if not there, you need to add/map it in Data Service output
