Unable to package : Build failed

I have two maps to package, Map 1- test2 and Map2- test3 respectively.
I am able to package the map separately but not combined.

I’m unable to package the project when i have two maps. here is the log file.

Here is the error:

‘test3’ is not a standard unreal filename or a long path name. Reason: Path should start with a ‘/’
