Not specifying opacity and/or colorOptions leads to error

[frousseu]

Hello!

An error occurs if argument colorOptions is not given when opacity is. Here is an example from the help file:

 library(leaflet)
 library(leafem)
 library(stars)

  tif = system.file("tif/L7_ETMs.tif", package = "stars")
  x1 = read_stars(tif)
  x1 = x1[, , , 3] # band 3

  leaflet() %>%
    addTiles() %>%
    leafem:::addGeoRaster(
      x1
      , opacity = 1
    )

##   Error in evalAll(list) : 
##    promise already under evaluation: recursive default argument reference or earlier problems?

The same error arises if both opacity and colorOptions are not specified. This is with R 4.0.4 and leafem 0.1.3 on Windows.

Thanks!

I should add that only specifying colorOptions and not opacity does not lead to an error.

Can you please try with remotes::install_github("r-spatial/leafem")?

With the GitHub version it works
