Cannot read property 'currentStyle' of null

[jirmed]

If I use a databinding for the property titleText to the main JSON model defined in manifest.json (in my case {/name}) the title is displayed correctly but following error is in the console:

Uncaught TypeError: Cannot read property 'currentStyle' of null at Object.helpers.getStyle (Chart.js?eval:5796) at Object.helpers.getMaximumWidth (Chart.js?eval:5781) at Chart.Controller.resize (Chart.js?eval:3980) at listener (Chart.js?eval:4448) at eval (Chart.js?eval:10445) helpers.getStyle @ Chart.js?eval:5796 helpers.getMaximumWidth @ Chart.js?eval:5781 resize @ Chart.js?eval:3980 listener @ Chart.js?eval:4448 (anonymous) @ Chart.js?eval:10445 requestAnimationFrame (async) notify @ Chart.js?eval:10442 resize (async) (anonymous) @ scrollbarSize.js?eval:6 w.fireThemeChanged @ Core.js?eval:6 c @ ThemeCheck.js?eval:6 (anonymous) @ jquery.sap.script.js?eval:6 setTimeout (async) e.sap.delayedCall @ jquery.sap.script.js?eval:6 c @ ThemeCheck.js?eval:6 (anonymous) @ jquery.sap.script.js?eval:6 setTimeout (async) e.sap.delayedCall @ jquery.sap.script.js?eval:6 c @ ThemeCheck.js?eval:6 (anonymous) @ jquery.sap.script.js?eval:6 setTimeout (async) e.sap.delayedCall @ jquery.sap.script.js?eval:6 c @ ThemeCheck.js?eval:6 (anonymous) @ jquery.sap.script.js?eval:6 setTimeout (async) e.sap.delayedCall @ jquery.sap.script.js?eval:6 c @ ThemeCheck.js?eval:6 (anonymous) @ jquery.sap.script.js?eval:6 setTimeout (async) e.sap.delayedCall @ jquery.sap.script.js?eval:6 c @ ThemeCheck.js?eval:6 (anonymous) @ jquery.sap.script.js?eval:6 setTimeout (async) e.sap.delayedCall @ jquery.sap.script.js?eval:6 c @ ThemeCheck.js?eval:6 (anonymous) @ jquery.sap.script.js?eval:6 setTimeout (async) e.sap.delayedCall @ jquery.sap.script.js?eval:6 c @ ThemeCheck.js?eval:6 fireThemeChangedEvent @ ThemeCheck.js?eval:6 w.loadLibrary @ Core.js?eval:6 (anonymous) @ Interface.js?eval:6 loadDependencies @ Manifest.js?eval:6 init @ Manifest.js?eval:6 i.init @ ComponentMetadata.js?eval:6 h._initCompositeSupport @ Component.js?eval:6 (anonymous) @ ManagedObject.js?eval:6 constructor @ ManagedObject.js?eval:6 constructor @ Component.js?eval:6 constructor @ UIComponent.js?eval:6 n @ Metadata.js?eval:6 a @ Component.js?eval:6 sap.ui.component @ Component.js?eval:6 l._createComponent @ ComponentContainer.js?eval:6 l.onBeforeRendering @ ComponentContainer.js?eval:6 r._handleEvent @ Element.js?eval:6 n @ RenderManager.js?eval:6 renderControl @ RenderManager.js?eval:6 s.render @ ShellRenderer.js?eval:6 renderControl @ RenderManager.js?eval:6 render @ RenderManager.js?eval:6 l.rerender @ UIArea.js?eval:6 w.renderPendingUIUpdates @ Core.js?eval:6 w.init @ Core.js?eval:6 (anonymous) @ Core.js?eval:6 s @ SyncPoint.js?eval:6 finishTask @ SyncPoint.js?eval:6 (anonymous) @ Core.js?eval:6 (anonymous) @ Core.js?eval:6 Promise.then (async) w._boot @ Core.js?eval:6 (anonymous) @ Core.js?eval:6 s @ SyncPoint.js?eval:6 finishTask @ SyncPoint.js?eval:6 (anonymous) @ Core.js?eval:6 Promise.then (async) constructor @ Core.js?eval:6 (anonymous) @ Core.js?eval:7 (anonymous) @ sap-ui-core.js:55 requireAll @ sap-ui-core.js:55 defineModule @ sap-ui-core.js:55 define @ sap-ui-core.js:55 (anonymous) @ Core.js?eval:6 execModule @ sap-ui-core.js:55 requireModule @ sap-ui-core.js:55 requireSync @ sap-ui-core.js:55 (anonymous) @ sap-ui-core.js:60
