Description

Hello,

I am experiencing an issue when calling refit on a test dataframe object. I've called this multiple times in the past and never experienced this issue and am unsure how to proceed to correct the error. This is the error that is printed when I call refit on my test tsibble,

Error in `mutate()`:
ℹ In argument: `arima = (function (object, ...) ...`.
Caused by error in `wrap_arima()`:
! wrong length for 'fixed'

Here's my code,

library(tidyverse)
library(dplyr)
library(ggplot2)
library(extrafont)
library(ggh4x)
library(ggpubr)
library(tsibble)
library(fable)
library(fabletools)
library(feasts)

market_df <- read_csv("./market_data.csv")

market_ts <-
  market_df |>
  as_tsibble(index = date,
             key = c(market, state, census_region, region, sb_region))
train <- filter(market_ts, date <= "2023-05-25")
test <- filter(market_ts, date > "2023-05-25")

linear_fits <- train |>
  model(
    tslm = TSLM(appointment_value ~ national_tv + local_tv + youtube + radio + meta + search + liposuction + season() + trend()),
    tslm_lipo = TSLM(appointment_value ~ national_tv + local_tv + youtube + radio + meta + search + liposuction + season_week + season_year),
    arima = ARIMA(appointment_value ~ national_tv + local_tv + youtube + radio + meta + search + liposuction, stepwise = FALSE)
  )

linear_fits |>
 refit(test)
  accuracy()

Research direction

Start by reproducing the supplied R example using the train and test tsibbles, the ARIMA model, and refit(test), then inspect the reported wrap_arima() failure and the surrounding refit path. The report names no repository file or test; done means identifying why the fixed parameter length is wrong and confirming that the supplied refit call completes without this error.
