Error on VSCode debug

Hello, I’m getting this error, when I try to debug source code in VS Code:

github.com/brocaar/chirpstack-application-server/internal/storage c:\Projects\Lab\LoraWAN\Chirpstack\chirpstack-application-server-master\internal\api\storage\storage.go:120:14: undefined: migrations.Asset c:\Projects\Lab\LoraWAN\Chirpstack\chirpstack-application-server-master\internal\api\storage\storage.go:121:14: undefined: migrations.AssetDir

exit status 2

Process exiting with code: 1

Any ideas?
