nothing to commit, working tree clean Git Hub Action and R script

I'm trying to run this simple scraping script with Git Hub Action:

It simply takes a vector of ASIN, generates the URL for the Amazon product page and extract the name from the given xpath, then it generates a dataframe and export it as a .csv file.

I would like to run this script every hour and output a different .csv file

For the future I would like to run the script every 24h and within the action use the GMAIL api to send it via mail.

For now I'm just trying to figure out how to obtain the basic task

library(tidyverse)
library(tibble)
library(openxlsx)
library(gdata)
library(lubridate)
library(rvest)
library(stringr)
library(dplyr)
library(purrr)
library(plyr)


ua <-
  "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.90 Safari/537.36"




name_checker_2 <- function(asin) {
  url_compositor <- paste0("https://www.amazon.it/dp/", asin)
  
  system('sleep 15')
  
  page <- read_html(url_compositor, user_agent = ua)
  
  name <- page %>%
    html_nodes(xpath = "//*[@id='productTitle']/text()") %>%
    html_text()
  
  name <- trimws(name)
  
  asin_2 <- unlist(asin)
  
  final <- cbind(asin, asin_2, name)
  
  final_df <<- as.data.frame(final)
  
  return(final_df)
  
  print("DONE")
  
}



asin <- c(
  "B07JVLQ38M",
  "B08LVXG2V1",
  "B07Y8DPHCL",
  "B082WSYYCX",
  "B082WSZXHB",
  "B09CTY5P2L",
  "B09SGB55N4",
  "B015O6A6GM",
  "B00G3DNXIE",
  "B07Y8DHN3F",
  "B015O6AFPE",
  "B00O4QVS66",
  "B093C19CSD",
  "B079Z9GXQS",
  "B09ZJ9QXZY",

)

date <- Sys.time()

scrape_raw <- purrr::map(asin, purrr::possibly(name_checker_2, NA))

product_name_df_delay_ua <- plyr::ldply(scrape_raw, data.frame)

write.csv(product_name_df_delay_ua, file = paste0("data/Amazon_name_",date,".csv"))

And this is my YAML file

The action run correctly the first time but the last run it gave me this error:
