Level is not a child of an existing mount point | Error on traveling between levels

Hello, I hope you all are doing well. How can I solve the error message in the log? I am running the following code snippet: GetWorld()->ServerTravel(OpenLevelText); and OpenLevelText stores the following value: Game/Battle_Royale/Levels/MainSessionMap?listen. The level that should redirect the player is called MainSessionMap. However, when I execute it, I get the following in the log: [2024.02.17-22.53.18:309][792]LogPackageName: Warning: DoesPackageExist called on PackageName that will always return false. Reason: Input 'Game/Battle_Royale/Levels/MainSessionMap' is not a child of an existing mount point. The level is stored locally in the following path: C:/Users/flueg/Documents/Unreal Projects/TeamTP/Content/Battle_Royale/Levels/MainSessionMap.umap. Would be very grateful for help :pray:
