Can't get SetCurve to work - wrong relativePath

I create gameobjects at runtime and have the following hierarchy

node0 <- Animation component is here
|__node1
|     |__ node2
|             |___node3 <- Animation clip refers to this node
|__node4
        |__node5

Anyway I’m having bad luck at having the animation play. What should I put in the relativePath?

I think “node0/node1/node2/node3” is correct.

for example, in my case, “_6_15_t/Hips/RHipJoint/RightUpLeg/RightLeg”
