`process_orchestration` raises ValidationError of pydantic

Hi, when I try to do orchestration of a service, I get a ValidationError of pydantic. When I debug the code step by step, I realize that `authenticationInfo` couldn't get from core service Orchestration. It's actually null in the database and this doesn't cause an error in Java client. However when I debug and I even change the provider value orchestration response as `authenticationInfo = null`, error continue. Finally, I changed the provider value of orchestration response as `authenticationInfo = ""` and it was fixed. Even provider `authenticationInfo` is nonrequired, `process_orchestration` raises error. I'm sharing debugging screenshots.

`authenticationInfo` is returned from core service Orchestration and there is no exception in Java client
`authenticationInfo` couldn't get from service Orchestration
`authenticationInfo` couldn't get from service Orchestration and error raised from pydantic like below
`authenticationInfo` couldn't get from service Orchestration and I added it as null but error raised from pydantic like below,

Suivre le traitement de la orchestration response par process_orchestration, en se concentrant sur authenticationInfo et la validation Pydantic présentée dans le rapport. Reproduire le cas de valeur null et le comparer au cas de chaîne vide ; le travail est considéré comme terminé lorsqu’un authenticationInfo optionnel à null ne déclenche plus de ValidationError.
