object circle reference.
example:

let a = { };
let b= { ref: a };
a.ref = b;

a or b could not serialize.
check your code.

I'm seeing this problem too on version 1.1.134 and RN v0.44.3. I think it's because I'm using normalizr's denormalize method. Does anyone have any workarounds? I guess I could just pass the ID and denormalize in my component.
