Error in some dashboards

Hi,

scrolling down in some dashboards, here is the error:

anaplan.dashboard.DashboardWidget#_onUpdate

You may want to try the following

• Close this dialog  and continue to use the application.
• If this does not work, refresh your browser by clicking the  Reload  button in the toolbar.
• Close the browser, and re-open it.
•  

Could anyone help me in fixing this annoying error?

Thanks

Enrico
