API error with date format for gar_api_generator

What goes wrong

Calling gce_vm_delete or gce_vm_stop (googleComputerEngineR package) throws an error:

Request Status Code: 400
Error: API returned: Invalid value '2019-08-30T12:00:51.270-07:00'. Values must match the following regular expression: '[a-z](?:[-a-z0-9]{0,61}[a-z0-9])?|[1-9][0-9]{0,19}'

(The date/time here appears to be the current date/time. The problem seems to be the "T" in the date/time string.) Using R 3.6.1 in Rstudio on Debian Linux.

I am posting here because I tracked the error down to the underlying function, googleAuthR::gar_api_generator, but I cannot figure out where the date/time parsing error originates within that function.

Steps to reproduce the problem

Start a vm: vm <- gce_vm("vm-ssh")

Stop vm: gce_vm_stop(vm)

Or delete vm: gce_vm_delete(vm)

Expected output

No error

Actual output

Request Status Code: 400
Error: API returned: Invalid value '2019-08-30T12:00:51.270-07:00'. Values must match the following regular expression: '[a-z](?:[-a-z0-9]{0,61}[a-z0-9])?|[1-9][0-9]{0,19}'

Note that the vm does stop or is deleted, depending on the function called, despite the error.

Before you run your code, please run:

options(googleAuthR.verbose=2) and copy-paste the console output here.
Check it doesn't include any sensitive info like auth tokens or accountIds - you can usually just edit those out manually and replace with say XXX

No output
