test1<-filter(t1,Month1 >= yearmonth("2018 Nov"))

fit_train<- train %>%

arima = ARIMA(Sales),
lm = TSLM(Sales ~ trend() + season())
)

fc<-fit_train %>%
forecast(h=3)

accuracy(fc,t1)

Get an error here on last line > accuracy(fc,test1)
Error: Could not find response variable(s) in the fable: Sales

Please note have updated packages tsibble and fable but the error still persists can you please help. If i print out the fc and test1 object they both have the variable Sales.

sales

R wouldn't recognise uses sales as being the same as Sales.

Most likely you have a mismatch between package versions. Can you please try updating all your packages to the current CRAN versions.

To get any additional help you will need to provide a reproducible example.
