Fluid effector aligned with SDF

Hi,

I am trying to make SDF effector for fluid, that is directed into the center of SDF (for example sphere sucking in fluid)

Based on this:

I think the solution should look something like this:

However the fluid is mostly static, reacts when I move/scale the spehreSDF, but not constantly when its just static. What am I missing? Is there a good way how to debug/visualize fluid operators?

Thanks!
