restricted IJobParallelFor exception during raycast call

I am receiving a "
IndexOutOfRangeException: Index 1 is out of restricted IJobParallelFor range [0...0] in ReadWriteBuffer.
ReadWriteBuffers are restricted to only read & write the element at the job index. You can use double buffering strategies to avoid race conditions due to reading & writing in parallel to the same elements from a job." exception within this:

Code (CSharp):

1. JobHandle hoverJob = Entities
2.             .WithBurst()
3.             .ForEach((Entity entity
4.             , int entityInQueryIndex //Used for Concurrent ECB writing
5.             , ref HoverSystemComponent hoverSystem
6.             , ref PhysicsVelocity _physicsVelocity
7.             , ref Translation translation
8.             , in PhysicsMass _physicsMass
9.             ) =>
10.         {
11.             RaycastHit raycastHit = new RaycastHit();
12.             RaycastInput rayInput = new RaycastInput
13.             {
14.                 Start = translation.Value,
15.                 End = translation.Value - new float3(0, hoverSystem.hoverHeight, 0),
16.                 Filter = colFilter2
17.             };
18.             bool hit = collisionWorld.CastRay(rayInput, out raycastHit);
19.  
20.             if (hit)
21.             {
22.                 ...
23.             }
24.         }).ScheduleParallel(startAfter);

and it appears to be triggered in Library/PackageCache/com.unity.physics@0.5.1-preview.2/Unity.Physics/Collision/World/Broadphase.cs:590)
which is:
RigidBody body = m_Bodies[rigidBodyIndex];

Is there any way around this to get raycast calls to work inside of parallelfor jobs ?

 

Nevermind. It is fixed when using a read only reference of the collisionWorld.

 

Was about to say that.
