This error typically arises in the context of SAP Fiori applications and the SAPUI5 framework, particularly when there are inconsistencies or misconfigurations in the repository settings.
  Cause:
  
  Repository Configuration: The error may occur if the system is not correctly configured to recognize the available SAPUI5 repositories. This could be due to missing or incorrect entries in the configuration settings.
  Version Mismatch: If there are multiple versions of SAPUI5 libraries or repositories, the system may struggle to determine which ones to include in the index calculation.

  Check Repository Configuration:
  
  Go to the SAP Fiori Launchpad or the relevant configuration transaction (like /UI5/APP_INDEX).
