The broken path are
path: Engine/Transient.NiagaraScriptSource_60:NiagaraGraph_0.NiagaraNodeAssignment_0.SetVariables_663BA4A94B4F354821B4D4B0B1BB7692.NiagaraScriptSource_1.NiagaraGraph_0.NiagaraNodeParameterMapGet_0
How do I find these paths ? I explore Niagara Content in engine content. But I could not found which path cause error.
