Issues with use UniqueIds in Apply Edits (ArcGIS Enterprise 11.5)

[AYUSHYADAV]

Environment:

• Software: ArcGIS Enterprise v11.5
• Platform: Azure Cloud

  The Use Case: We are attempting to leverage the new v11.5 functionality to update records via a custom unique field in our database, bypassing the need for objectids or globalids. Specifically, we are utilizing the useUniqueIds parameter as outlined in the Apply Edits (Feature Service/Layer) documentation.

  The Problem: When we attempt the update using our unique field, the operation fails with the following error:

  "Parameter 'useUniqueIds' must be false when 'OIDFieldContainsHashValue' is false." 

  I have attached a screenshot of the full error response for your reference.

  

  Thank you for your help!
