Error when querying STAC with sits package tracedback to rstac

[daniel-althoff]

Hi, I use the sits package frequently and I noticed that it was working two days ago, and when I updated my packages it stop working when using the sits::sits_cube() function. It seems like the latest version of rstac might have created a conflict. I'm not completely sure though.

edit: I reverted to rstac 0.9.1_5 and it worked fine.

Just use any given roi, e.g.,

roi_sf = geobr::read_state('SC')

sits_cube(
  source = "AWS", 
  collection = "SENTINEL-S2-L2A-COGS", 
  roi = roi_sf %>% st_transform(crs = "wgs84"), 
  bands = c("B04",  "B08",  "CLOUD"), 
  start_date = as.Date("2022-09-15"), 
  end_date = as.Date("2022-10-15"), 
  progress = T)

Returns the following:

Error: lexical error: invalid char in json text. search_phase_execution_exceptio (right here) ------^

Hi @daniel-althoff,

Thanks for reporting. Indeed, there was a bug in rstac search function.

We fixed it. You can install using devtools::install_github("brazil-data-cube/rstac").

We will resubmit to CRAN this hotfix as soon as possible.
