Error while running fiori extended app from launchpad

Hi experts

I've extended MM_PC_APV Fiori app. When I try to run the app from launchpad I get this error:

Error: found in negative cache: 'ui/s2p/mm/purcontract/approve/Component.js' from /sap/bc/ui5_ui5/sap/ZMM_PC_APV/Component.js: TypeError: Unable to get property 'extend' of undefined or null reference

this is the error:

Suggestions will be really appreciated
