When opening an application detail page from App Manager, we see the error "App info not found. Click ok to go back to home page" along with Internal Server Error Description When opening an application detail page from App manager, it throws the below error message. This issue is seen only on application details page of installed application.

Error : Internal Server Error (500) along with "App info not found. Click ok to go back to home page".

Steps to Reproduce

1. Login to the instance. 2. Navigate to new Application Manager. 3. Search for the application in the search box and check the "Updates" tab. 4. Click on the app and notice it shows blank page with Internal Error 500 along with "App info not found. Click OK to go back to home page". 5. Repeat steps 3 and 4 a few times and then it will load the AppStore page.

Expected: Load the page in first click. Actual: It displays an error message mentioned. And loads only after trying few times.

Note : it might not be reproducible in all instances as it happens due to query against sys_upgrade_history table to retrieve all upgrade history logs for previous installation and if this table has millions of records then the query can take long time.

Workaround Switch to Classic App Manager --> There should be a "Switch to Classic App Manager" on the top right of the Application Manager ui page.
