Blueprint Runtime Error:

Blueprint Runtime Error: Accessed None trying to read property K2Node_DynamicCast_AsAnim_BP_Main1 from function: ‘ExecuteUbergraph_CharacterWeapons’ from node: Equip Weapon in graph: EventGraph in object: CharacterWeapons with description: Accessed None trying to read property K2Node_DynamicCast_AsAnim_BP_Main1

That means in Character weapons blueprint, in equip weapon node animation value/variable is missing. Some screenshots would be helpful.
