Fiori launchpage Tile error

Hi,

In Fiori Launchpage, Tile is not getting loaded properly and having errors as below. All the Roles are assigned.

Error:

Configuration contract consumption error inTarget Mappingsap.ui2.srvc.Error: sap.ui2.srvc.ChipInstance({oChip:sap.ui2.srvc.Chip({sChipUrl:"/sap/bc/ui5_ui5/ui2/ushell/chips/action.chip.xml"}),bFullscreen:false}): CHIP instance is just a stub

What could be the Error? and How to Trace the logs any what are the TCodes to trace Fiori Launchpage and Launchpad errors. Kindly let me know.

Thanks.
