• What is the cause and solution for SAP error message /UI5/APP_API123 - Do not specify a deviating UI5 Component Name than descriptor ID &1 ?

  The SAP error message /UI5/APP_API123 Do not specify a deviating UI5 Component Name than descriptor ID &1 typically occurs in the context of SAP Fiori applications when there is a mismatch between the UI5 component name specified in the application descriptor (manifest.json) and the actual component name being used in the application.
  Cause:
  
  
  Mismatch in Component Name: The error indicates that the component name defined in the manifest.json file does not match the expected component name. This can happen if:
  
  The id property in the manifest.json file is not aligned with the actual component name.
  The application is being called with a different component name than what is defined in the descriptor.
  
  
  
  Incorrect Configuration: There may be an incorrect configuration in the routing or the way the application is being launched.
  
  
  Deployment Issues: Sometimes, issues during deployment can lead to discrepancies in the component names.
  
  
  Solution:
  
  
  Check manifest.json: 
  
  Open the manifest.json file of your application.
  Verify the id property under the sap.app section. Ensure that it matches the expected component name.
  
  Example:
  "sap.app": {
      "id": "your.component.id",
      ...
  }
  
  
  Consistent Naming: Ensure that the component name used in the application launch (e.g., in the URL or in the routing configuration) matches the id defined in the manifest.json.
  
  
  Clear Cache: If you have made changes to the manifest.json, clear the browser cache or use a private/incognito window to ensure that the latest version of the application is being loaded.
  
  
  Check Launchpad Configuration: If you are using SAP Fiori Launchpad, check the configuration of the tile or target mapping to ensure that it points to the correct component name.
  
  
  Review Application Deployment: If the issue persists, review the deployment process to ensure that the application was deployed correctly and that there are no discrepancies in the component names.
