There are issues with the application's development, including small glitches and errors. We're in the process of continuously fixing to address these issues, and once resolved, the application will be ready. I've worked on this internal system application, and I'll give you an example of our specific challenge. There was an issue involving a complex query where data was stored and retrieved from the database. The application also had a reporting component that wasn't generating reports or collecting the required information for Excel reports. To address this, I made changes to the query. I focused on the data format issue encountered in the implementation class. However, when implementing these changes under a specific thread, the application server showed an exception. I also made adjustments to resolve the issue.
