I’m using PlayFab for some online presence, and it was working fine, until I’ve tried shipping build. And then the game crashed with “fatal error” message.
Here is the blueprint that I am using.
After couple of hours of debugging I’ve found out that it crashes at “LoginWithCustomID” node, and the message in the logs
LogOutputDevice: Error: Invalid object referenced by the PersistentFrame: 0x000001bf6399e102 (Blueprint object: Blueprint /Game/NekoGhostJump/Core/Framework/BP_PlayFab.BP_PlayFab, ReferencingProperty: ObjectProperty /Script/PlayFab.PlayFabBaseModel:responseData, Instance: BP_PlayFab_C /Engine/Transient.GameEngine_0:BP_GameInstance_C_0.BP_PlayFab_C_0, Address: 0x000001bf5a6dc2e0) - If you have a reliable repro for this, please contact the development team with it.
And the stack trace
It looks similar to [UE-51952] which is not resolved and no one knows why it’s happening.
Asked same question on PlayFab community and will update if anything comes up.
