Error message

create_resources(): third argument, if provided, must be a hash

What it means

Error "create_resources(): third argument, if provided, must be a hash" thrown in puppetlabs/puppet.

Source

Thrown at lib/puppet/parser/functions/create_resources.rb:67

        create_resources("@user", $myusers)

    Note that `create_resources` filters out parameter values that are `undef` so that normal
    data binding and Puppet default value expressions are considered (in that order) for the
    final value of a parameter (just as when setting a parameter to `undef` in a Puppet language
    resource declaration).
