Error in rstac::stac() Value '' is not a valid property name

[rokoeh]

I was following along the code in https://stacspec.org/en/tutorials/2-using-rstac-and-cql2-to-query-stac-api/ and it seems that this part is not running:

rstac::stac("https://planetarycomputer.microsoft.com/api/stac/v1") |>
  rstac::ext_filter(
    collection == "landsat-c2-l2" &&
      t_intersects(datetime, )
  )

Not sure I'm doing something wrong or if it is a bug

Complete code :

require(sf)
require(rstac)

ashe <- sf::read_sf(system.file("shape/nc.shp", package = "sf"))[1, ]




ashe_bbox <- ashe |>
  sf::st_transform(4326) |>
  sf::st_bbox()

stac_query <- rstac::stac(
  "https://planetarycomputer.microsoft.com/api/stac/v1"
) |>
  rstac::stac_search(
    collections = "landsat-c2-l2",
    bbox = ashe_bbox,
    datetime = "2021-01-01/2021-01-31"
  ) |>
  rstac::get_request()


#stac_query




lapply(stac_query$features, \(x) names(x$properties)) |> 
  unlist() |> 
  unique()



lapply(
  stac_query$features, 
  \(x) data.frame(id = x$id, platform = x$properties$platform)
) |> 
  do.call(what = rbind)




ashe_bbox_geojson <- rstac::cql2_bbox_as_geojson(ashe_bbox)
#ashe_bbox_geojson


time_range <- rstac::cql2_interval("2021-01-01", "2021-01-31")
#time_range



rstac::stac("https://planetarycomputer.microsoft.com/api/stac/v1") |>
  rstac::ext_filter(
    collection == "landsat-c2-l2"
  )




rstac::stac("https://planetarycomputer.microsoft.com/api/stac/v1") |>
  rstac::ext_filter(
    collection == "landsat-c2-l2" &&
      t_intersects(datetime, )
  )
