[Bug]: Agentscope will throw an error when OpenAI model providers' services are missing certain non-essential fields.

Some model providers may omit certain parameters in their responses, which can cause Agentscope to throw an error.

Note: Some response parameters are not exposed as they are not relevant to IdeaLab. The specific differences are as follows:

id, object, created, model, system_fingerprint: not provided
choices: consistent with OpenAI, but logprobs is omitted when null
usage: consistent with OpenAI

Exception:

Caused by: com.openai.errors.OpenAIInvalidDataException: `id` is not set
