ff_rosters() not working for ESPN leagures

[WMRobin]

Describe the bug

The ff_rosters() function is not working for my ESPN league, and at least one other individual has had this issue.

Reprex Load library and open connection:

# install.packages("ffscrapr", repos = c("https://ffverse.r-universe.dev", getOption("repos")))
library(ffscrapr)

# open espn connection
conn <- espn_connect(
  season = Sys.getenv("current_season"),
  league_id = Sys.getenv("league_id"),
  espn_s2 = Sys.getenv("my_espn_2"),
  swid = Sys.getenv("my_swid"),
  user_agent = "Name"
)

I'm using an R project with current_season, league_id, my_espn_2, and my_swid saved to the project's profile.

The following code reads my league's rosters for week 1:

starters_1 <- ff_starters(conn, week = 1)
head(starters_1)
# A tibble: 6 × 12
   week franchise_id franchise_name  franchise_score lineup_slot player_score
  <int>        <int> <chr>                     <dbl> <chr>              <dbl>
1     1            1 Pineapple Juice            102. QB                  14.2
2     1            1 Pineapple Juice            102. RB                  10.8
3     1            1 Pineapple Juice            102. RB                  26.8
4     1            1 Pineapple Juice            102. WR                   8.2
5     1            1 Pineapple Juice            102. WR                   3.6
6     1            1 Pineapple Juice            102. TE                   8.5
# ℹ 6 more variables: projected_score <dbl>, player_id <int>, player_name <chr>,
#   pos <chr>, team <chr>, eligible_lineup_slots <list>

However, when doing the same for week 2, I get the following error:

starters_2 <- ff_starters(conn, week = 2)
head(starters_2)

Error in `map2()`:
ℹ In index: 1.
ℹ With name: 2.
Caused by error in `dplyr::mutate()`:
ℹ In argument: `projected_score = purrr::map2_dbl(...)`.
Caused by error in `purrr::map2_dbl()`:
ℹ In index: 1.
Caused by error in `pluck_raw()`:
! Index 1 must have length 1, not 2.
Run `rlang::last_trace()` to see where the error occurred.

Expected behavior I expected the function to return my league's starters for week 2, as it did for week 1.

For more context, this issue is not unique to ff_starters(). The same issue occurs with espn_potentialpoints(), so maybe this is a result of something affecting all data for weeks > 1. To be clear, I get the following output using the same connection as the reprex above:

espn_potentialpoints(conn, week = 1)

this issue is not unique to ff_starters()

not quite, potentialpoints calls ff_starters as its very first line https://github.com/ffverse/ffscrapr/blob/main/R/espn_potentialpoints.R#L22

There's been a bit of ESPN API wonkiness as of late. I encountered this: https://github.com/cwendt94/espn-api/discussions/575
