The getThisCompositeInstanceName function must be called from an operator instance. This requirement excludes static type definitions and the config clause of a composite definition.

A call to the getThisCompositeInstanceName function can be used only from within an operator instance. The static types and the config clause of a composite operator are definitions. They are not instances. Therefore, the getThisCompositeInstanceName function cannot be called from this location.
Remove the call to the getThisCompositeInstanceName function.
