robyn_refresh fails to plot refreshed results when plot_folder is specified

Project Robyn

Describe issue

I am trying to refresh a Robyn model persisted to JSON. The (re)training went fine, but R displays an error when trying to save refreshed plots and CSVs to file. Here is the code I ran.

data("dt_prophet_holidays")

df <- read_csv("data/DesignHome_ANDROID.csv") %>%
    mutate(INSTALL_DATE = as.Date(INSTALL_DATE, format="%Y-%m-%d"))

RobynRefresh <- robyn_refresh(
    json_file = json_file,
    dt_input = df,
    dt_holidays = dt_prophet_holidays,
    plot_folder = "robyn_results/refresh_attempt",
    refresh_steps = 7,
    refresh_iters = 700, # 1k is an estimation
    refresh_trials = 5
)

And here is a screenshot of the error.

Most output is generated and present, except the files prefixed report_*. There are no report_decomposition.png and report_actual_fitted.png; the associated CSVs are absent, too.

This problem disappears if I do not specify a plot_folder when calling robyn_refresh.

Provide reproducible example

Here is the obfuscated CSV containing refreshed data, along with a JSON file of the model I intend to refresh. (Extension .json changed to .txt, so that GitHub would allow the upload.)

Thanks for reporting this issue and special thanks for sharing a reproducible example; without it would have been pretty hard to debug. That said, I've deployed a fix into the master branch that should take care of this case. Can you please update Robyn to the latest dev version, retry, and let me know if it ran OK?

Robyn is now producing all expected output files. Thanks for the quick fix!
