The AI assistant is set to deepseek-v4-pro or deepseek-v4-flash, but cannot output the corresponding response.Output the error message: 'Error: Failed to create AI stream'

But when I set the AI assistant to deepseek-chat, it can output content, but it can only search for the question and cannot effectively retrieve the corresponding answer.
