Resolution
In this example, the directory identified in the health check error is referenced in ./custom/Accounts/Ext/JSGroupings/ directory.
This error will occur if any of the following directory names are present in a module at the ./custom/Extension/modules/{module name}/Ext/ directory level and they also contain PHP files with contents:

These directories, along with any files or directories in them are not supported for upgrade to your target versiuon and will need to be moved to a different directory level before proceeding with the upgrade. It is recommended that the offending directory be relocated to ./custom/Extension/modules/{module name}/Ext/Disabled/ in order to preserve the custom files so that they can be referenced when developing comparable customizations after the upgrade completes. Once the directories are relocated, you will need to run a system repair by going to Admin > Repair > Quick Repair and Rebuild. Please note that changing the file path of these directories will cause the corresponding customizations to be non-functional once the repair completes.
