• What is the cause and solution for SAP error message /UI5/APP_API148 - Number of app index entries not created because of missing manifest: &1 ?

  The SAP error message /UI5/APP_API148 indicates that the application index entries for a UI5 application could not be created due to a missing manifest file. The manifest file is crucial for UI5 applications as it contains metadata about the application, including configuration settings, dependencies, and routing information.
  Cause:
  The error typically occurs due to one of the following reasons:
  
  Missing Manifest File: The manifest.json file is not present in the application's directory.
  Incorrect Path: The application might be referencing the manifest file incorrectly, leading to it not being found.
  Deployment Issues: The application may not have been deployed correctly, resulting in missing files.
  File Permissions: There may be permission issues preventing the system from accessing the manifest file.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check for Manifest File:
  
  Ensure that the manifest.json file exists in the root directory of your UI5 application. The typical path is webapp/manifest.json.
  
  
  
  Verify Path and Naming:
  
  Confirm that the file is named correctly (manifest.json) and is located in the expected directory. The path should be relative to the application's root.
  
  
  
  Deployment Verification:
  
  If the application is deployed on a server, check that the deployment was successful and that all necessary files, including the manifest, were included.
  
  
  
  Check File Permissions:
  
  Ensure that the necessary permissions are set for the application directory and files, allowing the system to read the manifest file.
  
  
  
  Rebuild the Application:
  
  If you have made changes to the application structure or files, consider rebuilding the application to ensure that all components are correctly generated.
  
  
  
  Check for Errors in the Manifest:
  
  If the manifest file exists but is not valid (e.g., syntax errors), it may cause issues. Validate the JSON structure of the manifest file.
  
  
  
  Clear Cache:
  
  Sometimes, clearing the browser cache or the application cache can resolve issues related to outdated files.
  
  
  
  Related Information:
  
  SAP UI5 Documentation: Refer to the official SAP UI5 documentation for more details on the structure and requirements of the manifest.json file.
  SAP Community: Engage with the SAP Community forums for additional insights and solutions from other developers who may have encountered similar issues.
