Does it support Deepseek-R1?

I set openai url to deepseek r1 671B, but it occurs the error that "Object not generated according to schema, fallback to manual parsing
Both JSON and Hjson parsing failed: Error: source is not a string"
The complete error trace log is:
Object not generated according to schema, fallback to manual parsing
Both JSON and Hjson parsing failed: Error: source is not a string
