Scheduling a job issue

Question

I'm trying to schedule a job for my ECS system, I'm following the docs on ECS docs specifically the handling of the job:

         protected override JobHandle OnUpdate(JobHandle inputDeps)
         {
             MovementJob moveJob = new MovementJob
             {
                 topBound = GameManager.GM.topBound,
                 bottomBound = GameManager.GM.bottomBound,
                 deltaTime = Time.deltaTime
             };
 
             JobHandle moveHandle = moveJob.Schedule(this, 64, inputDeps);
 
             return moveHandle;
         }

When trying to schedule this job on my own class I get this error: alt text even though the plant system derives from the job component system public class PlantSystem : JobComponentSystem

Full code:

 public class PlantSystem : JobComponentSystem
 {
     [Unity.Burst.BurstCompile]
     struct PlantJob : IJobProcessComponentData<Position, Plant>
     {
         public float health; 
         public void Execute(ref Position data0, ref Plant data1)
         {
             if(data1.health < 10000)
             {
                 float data2 = data1.health;
                 data1.health = data2 + 1;
             }
         }
     }
 
     protected override JobHandle OnUpdate(JobHandle inputDeps)
     {
         PlantJob plantJob = new PlantJob
         {
             health = 1.0f
         };
         return plantJob.Schedule(this, 64, inputDeps);
     }
 }

Well, now I'm testing with 10 000 simple spheres, and I noticed it makes a big difference to have the material checked with enable GPU instancing. With that on I get about 30 FPS with a low end machine I was also worried about if there is no batching at all without that Schedule integer argument , but I don't know how to check that

My code to create entities is created from watching tutorials, mostly from Samuli Natri's ECS youtube tutorial and blog. https://samulinatri.com/blog/unity-ecs-entity-component-system/ and also some other tutorials around
