Utility for package exactextractr, which has non-exportable objects

[GatesDupont]

One package with non-exportable objects is exactextractr, which offers the fastest raster extractions.

On your page, https://future.futureverse.org/articles/future-4-non-exportable-objects.html, you asked people report such instances.

Thanks for sharing. I'd love to add this to the list, but I'd probably need your help since I'm to well versed in the spatial field. What I need it a minimal reproducible example that illustrate the problem. Maybe some similar to the example for raster that results in:

f <- future({
  print(dim(r))
  print(dim(s))
})
Error: Detected a non-exportable reference ('externalptr') in one of the
globals ('s' of class 'RasterLayer') used in the future expression
