This method is deprecated or moved on the latest stable version. The last existing version (v7.0.0) is shown here.

These similar methods exist in v7.1.3.2:

ActiveRecord::Reflection::AssociationReflection#association_primary_key

association_primary_key(klass = nil) public

We want to use the klass from this reflection, rather than just delegate straight to the source_reflection, because the source_reflection may be polymorphic. We still need to respect the source_reflection’s :primary_key option, though.
