I can't Understand these errors

I;ve created some weapons and feeding them in my array when my character picks the weapon the object reference array set on my third person BP then i’m over lapping my character to a podium to attach my sword to a podium every thing is going fine but I don’t know why my cast is failing and these errors are showing on my screen

i’ve also created class reference in PodiumSword_BP

Blueprint Runtime Error: “Accessed None trying to read property K2Node_DynamicCast_AsThird_Person_Character”. Blueprint: PodiumSword_BP Function: Execute Ubergraph Podium Sword BP Graph: ForEachLoop Node: Branch

Blueprint Runtime Error: “Accessed None”. Blueprint: PodiumSword_BP Function: Execute Ubergraph Podium Sword BP Graph: ForEachLoop Node: Branch

Thank you !

I’ve added a delay node before before casting a third person character and my issue got solved

Can someone provide me tasks assigments related to arrays so can keep my learning up and running please
Thanks
