Failure to add IPP Everywhere queue

[jamesps-ebi]

Given: Ubuntu 20.04, Puppet 6.24, cups 2.3.1, leoarnold-cups 2.0.3
When: I apply the below manifest with the given hiera data

class hg_workstation::profile::common
{

  # CUPS printer configuration
  include cups

}

---
cups::default_queue: 'Follow_You'
cups::web_interface: true
cups::resources:
  Follow_You:
    ensure: 'printer'
    uri: 'ipps://example.com:9164/printers/follow_you'
    model: 'everywhere'
    enabled: true
    accepting: true
    options:
      - auth-info-required: 'username,password'

In order to: add a new IPP everywhere network printer.
Then: I get the below error.

info	//ubu20-n-495753433f.ebi.ac.uk/Puppet	Applying configuration version '1636725815'
err	//laptop-01/Puppet	Execution of '/usr/sbin/lpadmin -E -p Follow_You -m everywhere' returned 1: lpadmin: Printer drivers are deprecated and will stop working in a future version of CUPS.

lpadmin: Unable to copy PPD file.

Running the lpadmin command from the error message produces the same error about printer driver deprecation.
However, that command seems to be missing some parameters that were specified in hiera.

The following command is what I would expect to be run:
lpadmin -p 'Follow_You' -m 'everywhere' -v 'ipps://example.com:9164/printers/follow_you' -E -o auth-info-required=username,password
The above command, when run manually, correctly adds the printer with the required settings.

This may be an unforeseen edge case with the lpadmin binary. My hunch is that

lpadmin -E -p 'Follow_You' -m 'everywhere'

fails, while

lpadmin -E -p 'Follow_You' -m 'everywhere' -v 'ipps://example.com:9164/printers/follow_you'

passes because a destination was provided. @jamesps-ebi Could you please confirm?

I think lpadmin is trying to contact the print server synchronously in order to fetch the configuration data. And in this is /dev/null due to how the module currently works:

puppet-cups/lib/puppet/provider/cups_queue/cups.rb

Lines 70 to 73 in b498e37

	# Create a minimal raw queue first, then adapt it
	lpadmin('-p', name, '-v', 'file:///dev/null')
	run_parameter_setter(:model, :ppd)

A first cursory investigation suggests that -m and -v parameters must appear in the same commandline invocation, or else lpadmin will fail.

This may be an unforeseen edge case with the lpadmin binary. My hunch is that

lpadmin -E -p 'Follow_You' -m 'everywhere'

fails, while

lpadmin -E -p 'Follow_You' -m 'everywhere' -v 'ipps://example.com:9164/printers/follow_you'

passes because a destination was provided. @jamesps-ebi Could you please confirm?

Yes, testing both of those commands in my environment, lpadmin -E -p 'Follow_You' -m 'everywhere' fails, while lpadmin -E -p 'Follow_You' -m 'everywhere' -v 'ipps://example.com:9164/printers/follow_you' is successful.

So specifying the URL for the printer in the same command seems to be required, at least while using the 'everywhere' driver.

So is there a potential workaround for adding IPP Everywhere printers? Or is it impossible to add a printer like this with the current module?
