Cannot read attribute property of undefined "Entity Structure"
After I created a Business Process, somehow it caused my custom page "Concert Programs" to lose the list of values/records and they no longer display. I deleted the process hoping this would fix it, but have not been able to fix the issue. My custom page gets the error in the screenshot. (Cannot read "attribute" property of undefined) . I investigated the code which I also have a screenshot and it appears my custom entity "UsrConcertPrograms" is missing from the list. Can you point me in the direction to resolve? Thank you.
