Fiori LaunchPad get error when launching

[newBie2]

I get below error after login to Fiori Launchpad, this message come from sap.base.ManagedObject-dbg.js, i don't find any same case of this in community. Can expert help me solve this. 
UI5 version: 1.120.0

error: Defining the object type ('sap.m.PageAccessibleLandmarkInfo') via its string name is deprecated, since it leads to accesses to the global namespace. The object type either stems from an explicitly given 'Type' value or was inferred from the default aggregation type. Please require the respective object type module beforehand. For control development, please also refer to the runtime metadata property 'defaultClass', which allows you to specify a default aggregation class type via constructor reference.
