Also happens for OpenAIChatCompletionResponse: Caused by: kotlinx.serialization.MissingFieldException: Field 'object' is required for type with serial name 'ai.koog.prompt.executor.clients.openai.models.OpenAIChatCompletionResponse', but it was missing

Will close #749 as a duplicate of this issue for now.
