Create a price-triggered order that sells market #21

I'm encountering an issue with the GateIO REST API when calling the /spot/price_orders endpoint to create a price-triggered order. I'm attempting to set type=market and time_in_force=IOC to execute a market sell order when the price reaches or exceeds the target price. However, the server consistently returns an INVALID_PARAM error without additional details. Could you assist in identifying the cause of this error or suggest the correct parameters for creating a price-triggered market sell order?

Thank you!
