Dashboards: "Tab is broken"Issue When you open a tab in certain Dashboard it will show you "Tab is broken"CauseThis issue arises when the "Canvas page" is empty for that tab in pa_tabs table.ResolutionThe solution would be to manually add the canvas page back for each of the tabs in the instances. To add them back in the other instances:1. Navigate to pa_tabs.list2. Search for the tab(where you are seeing the error)3. Add the Canvas Page to the Personalized List Column.4. The Canvas Page should be empty.5. Add PA tab.
