  The SAP error message /UI5/APP_API136 Descriptor Id &1 is not unique typically occurs in the context of SAP Fiori applications or SAPUI5 development. This error indicates that there are multiple entries with the same descriptor ID in the application descriptor files, which should be unique.
  Cause:
  
  
  Duplicate Descriptor IDs: The most common cause of this error is that there are multiple entries in the manifest.json or other configuration files where the descriptor ID is defined. This can happen if:
  
  You have multiple components or modules defined with the same ID.
  There are conflicting entries in the application configuration.
  
  
  
  Incorrect Configuration: Sometimes, the error can arise from incorrect or incomplete configuration in the application files, leading to ambiguity in identifying the components.
  
  
  Solution:
  
  
  Check for Duplicates:
  
  Open the manifest.json file of your SAPUI5 application.
  Look for the sap.app section and check the id property. Ensure that it is unique across your application.
  If you have multiple components or modules, ensure that each has a unique descriptor ID.
  
  
  
  Review Component Definitions:
  
  If you are using multiple components, check their definitions in the manifest.json or any other relevant configuration files.
  Ensure that each component has a unique ID and that there are no overlaps.
  
  
  
  Clear Cache:
  
  Sometimes, the error may persist due to caching issues. Clear the browser cache or the SAP Fiori Launchpad cache to ensure that the latest version of the application is being loaded.
  
  
  
  Check for Dependencies:
  
  If your application depends on other libraries or components, ensure that there are no conflicting IDs in those dependencies.
  
  
  
  Debugging:
  
  Use the browser's developer tools to inspect the network requests and console logs. This can provide additional context on where the duplication might be occurring.
  
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for guidelines on structuring your manifest.json and best practices for SAPUI5 application development.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and how they resolved them.
