puppetlabs-f5 virtualserver can't process a provider parameter

When following the documentation, particularly this part: https://forge.puppet.com/puppetlabs/f5/1.5.0/readme#step-one-classifying-your-servers

running

puppet device -v --user=root

produces the following output:

Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: no parameter named 'provider' at /etc/puppetlabs/code/environments/<envname>/modules/profile/manifests/f5_device.pp:26 on F5_virtualserver[/Common/puppet_vs] at /etc/puppetlabs/code/environments/<envname>/modules/profile/manifests/f5_device.pp:26 on node bigip

[...]

Error: /Stage[main]/Profile::F5_device/F5_virtualserver[/Common/puppet_vs]: Could not evaluate: f5_virtualserver requires that a provider is declared. Available providers are: forwarding_ip, forwarding_layer_2, performance_http, performance_l4, reject, standard, stateless

Nodes and pools are being created/enforced as expected. I'm using the example code from the documentation.
