When I try to create a single stat using Javascript I’m getting this issue.
TypeError: Cannot read property 'length' of undefined at e.upgradeToGridLayout (dashboard_migration.ts:484) at e.updateSchema (dashboard_migration.ts:423) at e.updateSchema (dashboard_model.ts:795) at new e (dashboard_model.ts:90) at t.create (dashboard_srv.ts:132) at t.setupDashboardInternal (dashboard_ctrl.ts:155) at t.setupDashboard (dashboard_ctrl.ts:145) at t.init (history.ts:67) at t.e.initDashboard (grafana_app.ts:66) at app.4f5454f867a0cc2fe8dd.js:30978 true
