modifyOrder api cannot modify size

[boyi]

Hello,
I use the modify Order API, and send correct params of size and price to it, the server just returned:

APIError: status=400, message=Must modify either price or size

Seems like the size is never sent to the ftx server. can you look into that?

type RequestForModifyOrder struct {
OrderID string json:"-"
ClientID string json:"-"
Price float64 json:"price,omitempty"
Size float64 json:"side,omitempty"
}

the Size json is a typo "side"
