gce_vm() dry_run fails

[LukasWallrich]

I tried to use dry_run = TRUE within gce_vm() to get the JSON - and it returns Error: $ operator is invalid for atomic vectors

This happens with the following command:

gce_vm(template = "rstudio",
                name = "rstudio-iat2",
                zone = "europe-west4-a",
                username = "me", password = "mine",
                predefined_type = "e2-highmem-4",
                dry_run = TRUE)

I tried to chase this down further - and return(toJSON(the_instance, pretty = TRUE)) in gce_vm_create() works, but then this breaks somewhere on the way back ...
