Description

Hi I am trying to use tar_quarto_raw() however I am getting an error 'x must be a language object'. This occurs even when I try to run the example code for tar_quarto_raw() (please see reprex below), despite updating to the latest versions of targets and tarchetypes.

Any advice would be much appreciate, thanks!

library(targets)
library(tarchetypes)

targets::tar_dir({ # tar_dir() runs code from a temporary directory.
  # Unparameterized Quarto document:
  lines <- c(
    "---",
    "title: report.qmd source file",
    "output_format: html",
    "---",
    "Assume these lines are in report.qmd.",
    "```{r}",
    "targets::tar_read(data)",
    "```"
  )
  # In tar_dir(), not part of the user's file space:
  writeLines(lines, "report.qmd")
  # Include the report in a pipeline as follows.
  targets::tar_script(
    {
      library(tarchetypes)
      list(
        tar_target(data, data.frame(x = seq_len(26), y = letters)),
        tar_quarto_raw("report", path = "report.qmd")
      )
    },
    ask = FALSE
  )
