Reprex with user-facing function:

library(epidatr)
ga_hhs_issue_data =
  covidcast(
    "hhs", "confirmed_admissions_influenza_1d",
    geo_type = "state", time_type = "day",
    geo_values = "ga", time_values = "*",
    issues = "*"
  ) %>%
  fetch_tbl()
#> Error in parse_timeset_input(time_values): Invalid timeset input: *
