Why does not my particle system collision work?

I have added a particle system where I have checked the collider option and added a world particle collider. See the image below.

In the script that is attached to the particle system I have:

void OnParticleCollision(GameObject other) {
    Debug.Log("Particle was hit!");
}

The bullets that are fired don´t seem to hit the particles since the above message is not printed. The bullets are spheres with a sphere collider and a rigidbody attached. The rigidbody is set to non-kinematic (the checkbox is not checked) if that matters.

Also, the bullet object has a script attached with the same lines as above:

void OnParticleCollision(GameObject other) {
    Debug.Log("Bullet was hit!");
}

But it is not printed as well.

What am I missing?

make sure that Send Collision Messages option is checked under the Collision tab.

Double check that you have this script attached to your particle system and not any arbitrary gameobject.

Check if you have "Is trigger" disabled on Sphere Collider, or you're particles too small and don't hit the actual collider. Tried to simulate your situation, all works fine.
