object of type ‘closure’ is not subsettable” error

Question

I have this base:

structure(list(id_mujer = c(12468, 13882, 15676, 182603, 182603, 
299864, 299864, 301483, 301483), primer_contacto = structure(c(1350345600, 
1347580800, 1339372800, 1330041600, 1330041600, 1335484800, 1335484800, 
1337644800, 1337644800), tzone = "UTC", class = c("POSIXct", 
"POSIXt")), segundo_contacto = structure(c(1351728000, 1376352000, 
1352764800, 1337212800, 1337212800, 1344988800, 1344988800, 1345075200, 
1345075200), tzone = "UTC", class = c("POSIXct", "POSIXt")), 
    tercer_contacto = structure(c(1553731200, 1530057600, 1556496000, 
    1439424000, 1439424000, 1373241600, 1373241600, 1387152000, 
    1387152000), tzone = "UTC", class = c("POSIXct", "POSIXt"
    )), positivo = c(NA, NA, NA, NA, "2015-08-13", "2012-08-15", 
    NA, "2012-08-16", NA)), row.names = c(NA, -9L), groups = structure(list(
    id_mujer = c(12468, 13882, 15676, 182603, 299864, 301483), 
    .rows = structure(list(1L, 2L, 3L, 4:5, 6:7, 8:9), ptype = integer(0), class = c("vctrs_list_of", 
    "vctrs_vctr", "list"))), row.names = c(NA, -6L), class = c("tbl_df", 
"tbl", "data.frame"), .drop = TRUE), class = c("grouped_df", 
"tbl_df", "tbl", "data.frame"))

The women's ids that are repeated is because they have a positive comment that says NA and another that is a date. What I want to do is convert the positive column into those id so that the 2 observations have the same date, and the observations that are only there once have the same result (in this case NA)

I do this and it doesn't work:

base %>%
mutate(positivo= if_else(!id_mujer %in% c(182603, 299864, 301483, 15676, 12468, 13882), 
                           positivo,
                           positivo[!is.na(positivo)]))

It gave this:

Error: Problem with `mutate()` column `positivo`.

i `positivo = if_else(...)`.

x objeto de tipo 'closure' no es subconjunto

i The error occurred in group 1: id_mujer = 12468.

Run `rlang::last_error()` to see where the error occurred.

The output I would like is this:

# A tibble: 6 x 5

# Groups: id_mujer [6]

id_mujer primer_contacto segundo_contacto tercer_contacto positivo
