总部老师：今天调用开单收银的接口提示
{"Result":{"ResponseStatus":{"ErrorCode":500,"IsSuccess":false,"Errors":[{"FieldName":"FPOS","Message":"字段“POS机”是必填项"},{"FieldName":"FGoodsEntity","Message":"分录实体“商品信息”是必填项"},{"FieldName":"AbstractInteractionResult","Message":"AbstractInteractionResult.InteractionContext is null"}]},"Id":""}}，按说提示消息已经很明确了，但是我检查了一下它提示的参数我都有传，是不是哪里没设置正确 望老师提供技术支持 谢谢
下面是我发送的json
