RaycastHit not returning null when no collider is detected
Hi all, It's my first time here so pardon me if i did anything wrong.
I have a simple SphereCastAll that prints the object's name when hit, like in my example, it hits the terrain.
if the array is not null, it will also log "in not null", before printing the object's name.
However when it does not hit anything, it does not return null but does not print anything as well other than saying it is in the "in not null" loop. Any idea what might be the cause? Thank you 
Below is my code snippet
void Update()
{
CheckIsOnEdge();
}
void CheckIsOnEdge()
{
//RaycastHit hitInfo;
RaycastHit[] allHit = Physics.SphereCastAll(edgeTrackerTrans.position, 0.1f, transform.forward, 0.1f);
if(allHit != null)
{
print("in not null");
foreach(RaycastHit hit in allHit)
{
print(hit.collider.gameObject.name);
}
m_Animator.applyRootMotion = true;
}
else
{
print("nothing hit");
}
}

SphereCastAll will always return an array. It will never return null. If no colliders were hit, it just returns an empty array. So you should do something like this instead:
if(allHit.Length > 0)
{
foreach(RaycastHit hit in allHit)
{
print(hit.collider.gameObject.name);
}
m_Animator.applyRootMotion = true;
}
else
{
print("nothing hit");
}
