【Unity】System::InvalidOperationException: The UNKNOWN_OBJECT_TYPE has been declared as [WriteOnly] in the job, but you are reading from it.

概要

System::InvalidOperationException: The UNKNOWN_OBJECT_TYPE has been declared as [WriteOnly] in the job, but you are reading from it.
This Exception was thrown from a job compiled with Burst, which has limited exception support.

Job System を使用している Unity プロジェクトで
上記の例外が発生する現象に遭遇した

using var list = new NativeList<double>( Allocator.Temp );

foreach ( var x in list )
{
}

NativeList に対して foreach を使用している箇所を

using var list = new NativeList<double>( Allocator.Temp );

for ( var i = 0; i < list.Length; i++ )
{
}

for に置き換えたら例外が発生しなくなった
