day_continue fails

[homerhanumat]

aor::day_continue("2022-12-02", "aoc2022/02_rock_paper_scissors/puzzle.R")

gives:

Error in UseMethod("xml_find_all") : 
  no applicable method for 'xml_find_all' applied to an object of class "NULL"
Error: [ENOENT] Failed to remove '/var/folders/3v/9bfvrwnn0gn50mfplb8xcchr0000gn/T/Rtmp9ump1s/fileb4c02836e3dc.html': no such file or directory

Working with the debugger, I find that the result of the httr GET request for the article tags is a list of length 1: the contents of the first article tag for the Part One puzzle. Hence purrr:pluck(part) gives NULL. (Two article tags are present when I view the site with the browser inspector, but that's after I solved the second problem.)

@homerhanumat Can you check if you have correctly exported your session cookie as an environment variable? Please refer to the (recently updated) README for instructions on how to do this: https://github.com/clente/aor#authentication

If the function still doesn't work for you, could you please post a reproducible example with reprex? It works fine on my machine :/

[homerhanumat]

Never had a problem getting the session cookie.

I reinstalled aor (this commit), and re-started R. Below is output from reprex::reprex(), except, of course, for token.

Caveat: My solution to Part 2 was accepted this morning. Below represents about the fifth or sixth time since then that I have run aor::day_continue(). Although the results has been the same every time, I cannot be sure how the site responds after multiple automatic requests.

If i can be of further help let me know. Thanks for looking into this.

@homerhanumat, I haven't been able to identify the cause of this bug. Does the code below work for you? If it doesn't, I think it isn't something I can fix from within aor :(

token <- "53616c..." # Replace with your token

"https://adventofcode.com/2022/day/1" |>
    httr::GET(httr::set_cookies(session = token)) |>
    httr::content(encoding = "UTF-8") |>
    xml2::xml_find_all("//article") |>
    purrr::pluck(2)
