Order cannot be placed

How did you pass the timestamp? It should be a Date or an ISO formatted string:

export interface OrderParam {
	amount: number
	limitPrice: number,
	orderType: OrderType,
	stopLossLimitPrice?: number,
	stopLossStopPrice?: number,
	stopPrice?: number,
	takeProfitLimitPrice?: number | null,
	underlyingIsin: string,
	expiresAt: Date | string
}

I passed it like you did in your Readme.md as string via validUntil. And I just took the value the Browser would send to the API so I don't think it is a formatting issue.

The readme might be wrong, try passing the date via expiresAt. I can try to reproduce it by next week, if that doesn't work.
