我试图每天预测数据 . 如果我在r中使用holtwinters函数，我收到警告消息而无法执行输出

我使用下面的代码

library(data.table)
library(forecast)
library(lubridate)

ruta = "D:\\datasets/"

dt_ts = fread(paste0(ruta,"Actuals.csv"))
dt_ts[,Dates:=as.Date(Dates,"%Y-%m-%d")]

# Removing 29 february
dt_ts = dt_ts[!Dates %in% as.Date("2016-02-29")]

regions = unique(dt_ts$Regions)
items = unique(dt_ts$Item)

ls_pred=list()
ls_model=list()
i<-regions[1]
j<-items[1]
for(i in regions){
  for(j in items){
    name_model = paste(i," - ",j)

    ts_temp = ts(dt_ts[Regions==i & Item==j,]$Data,frequency = 365,start = 
 c(2016,1,1))
    # plot(ts_temp)

    model_hw = HoltWinters(ts_temp)
    pred_hw = forecast(model_hw,h=365)
    # plot(pred_hw)

    pred_hw$mean = ifelse(pred_hw$mean<0,0,pred_hw$mean)
    # plot(pred_hw)

    ls_model[[name_model]] = model_hw
    ls_pred[[name_model]] = pred_hw$mean    


  }
}

我的数据如下
