Ruby codegen emits invalid `has_edge :` (empty edge name) for 5 ad objects

[crespire]

Description

The Ruby SDK codegen produces has_edge : with an empty edge name for 5 ad object classes. This is not a valid Ruby symbol literal and causes a SyntaxError at load time.

The Python codegen handles these same objects correctly, emitting named methods (genget/gendelete) with endpoint='/'.

Affected classes

Ruby file	Invalid output	Python SDK equivalent
ad_objects/ad_campaign_group.rb	has_edge : do |edge|	def genget(self, fields=..., params=...)
ad_objects/ad_campaign_placement.rb	has_edge : do |edge|	def genget(self, fields=..., params=...)
ad_objects/adgroup.rb	has_edge : do |edge|	def gendelete(self, fields=..., params=...)
ad_objects/product_catalog_apps_and_software_item.rb	has_edge : do |edge|	def gendelete(self, fields=..., params=...)
ad_objects/product_catalog_media_title.rb	has_edge : do |edge|	def gendelete(self, fields=..., params=...)

Expected behavior

The codegen should emit a named edge, e.g.:

has_edge :genget do |edge|
  edge.get 'AdCampaignGroupGet' do |api|
    api.has_param :fields, 'string'
  end
end

Actual behavior

has_edge : do |edge|
  edge.get 'AdCampaignGroupGet' do |api|
    api.has_param :fields, 'string'
  end
end

This raises SyntaxError: unexpected ':', expecting end-of-input when the file is loaded.

Impact

Currently low — these files are autoloaded and nothing references them, so the error is silent. However, this becomes a blocker for any consumer that needs to eager-load the gem (e.g., for thread-safety in Rails/Sidekiq environments) or for consumers that end up needing to use these edges.

Introduced in

Commit ff8f28dc ("Auto-generated ruby SDK code update", D95913002). These files have never had valid edge names.

In https://github.com/facebook/facebook-ruby-business-sdk/tree/v25.0.3 (and potentially other versions), facebook_ads/ad_objects/ad_campaign.rb has the same issue:
