# Multiple Entries With the Same BundleRelativePath
This is an error I got when publishing KeyKeeper commit `d22c5b103081536405e480ae1bd35730ae6d792b` with the following error message:
```
error MSB4018: The "GenerateBundle" task failed unexpectedly
error MSB4018: System.ArgumentException: Invalid input specification: Found multiple entries with the same BundleRelativePath
```
This has something to do with nuget packages referencing the same files, and publishing to a single exe file. See the following links for more details:

Happened after upgrading packages so the solution was to roll back that change. Research shows it has something to do with the Serilog package but I wasn't able to confirm this.
