dify添加自定义模型报错：Credentials validation failed: JSON decode error

[bevis12]

接口定义：
async def openai_chat_completion(
request: OpenAICompletionRequest,
authorization: Optional[str] = Header(None)
):

接口输出格式：
res = {
"id": "",
"object": "chat.completion.chunk",
"created": 0,
"model": model_name,
"choices": [{"index": 0, "delta": {"content": ""}, "logprobs":None, "finish_reason": None}]
}

I found an issue that might be helpful:

• Invalid Authorization token. This thread discusses an invalid authorization token, which may relate to the credentials validation error you are experiencing.
