Package Fails - Pair != nullptr assertion

Having an issue with packaging. Getting this error:

**MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd: Assertion failed: Pair != nullptr [File:D:\BuildFarm\buildmachine_++UE4+Release-4.11\Engine\Source\Runtime\Core\Public\Containers\Map.h] [Line: 520] **

From my searches, it’s usually caused by an invalid variable in a blueprint. Unfortunately, we have several hundred blueprints, and I’m not certain exactly what we’re looking for.

Is there any way to get more details on which blueprint is causing this, or fix the issue in a slightly less brute force way than manually reviewing every blueprint in the project for something weird?

Thanks in advance for any help you can provide!

Hi ,

Due to the large volume of questions and comments concerning the Engine, we did not have a chance to respond to your post at the time you submitted it and, thus, the issue is now outdated. If you are still experiencing this issue in the current release of the Engine, please make a new post for assistance.

Thanks,
