Invalid system method

A [Query] method cannot be emitted as a chunk-dispatched system. Compilation fails; the last good module keeps running.

Common causes

  • The query method is an instance method, returns a value or has generic parameters.
  • The query has no component column parameter; resources, context parameters and tag filters alone do not supply one.

Fixes

  • Declare a non-generic static void query method.

  • Include at least one supported component with fields as a query parameter, using ref for writes or in for reads.
