3776504 - Swagger ui occ endpoint loads very slow after migrating from ycommercewebservices-based extension to new occ extension

• After migrating a controller method from an extension generated via ycommercewebservices to a new OCC extension, expanding the custom api method in Swagger UI keeps loading and takes several minutes to render.
• The same endpoint loads quickly when served from the legacy ycommercewebservices-based extension.
• Switching the Swagger UI response media type between XML and JSON is also very slow (minutes to switch).
• The /occ/v2/api-docs content is generated and loads without errors.
