Puppet apply recursive copy of directory fails in file resource

Puppet Version: 6.14.0
Puppet Server Version: NA
OS Name/Version: Centos 7

In Puppet 6.14 copying a puppet served directory fails. Here is an example

 file { '/a':
  ensure  => 'directory',
  source  => "puppet:///modules/test",
  recurse => true,
  purge   => true,
}

Now fails with this error

[root@rcudb vagrant]# puppet apply test_case.pp
Notice: Compiled catalog for rcudb.example.com in environment production in 0.05 seconds
Notice: /Stage[main]/Main/File[/a]/ensure: created
Error: Could not set 'file' on ensure: Is a directory @ io_fread - /etc/puppetlabs/code/environments/production/modules/test/files
Error: Could not set 'file' on ensure: Is a directory @ io_fread - /etc/puppetlabs/code/environments/production/modules/test/files
Wrapped exception:
Is a directory @ io_fread - /etc/puppetlabs/code/environments/production/modules/test/files
Error: /Stage[main]/Main/File[/a/a.a]/ensure: change from 'absent' to 'file' failed: Could not set 'file' on ensure: Is a directory @ io_fread - /etc/puppetlabs/code/environments/production/modules/test/files

Desired Behavior:

With puppet version puppet-agent.x86_64 0:6.13.0-1.el7 This works as expected:

root@rcudb vagrant]# puppet apply test_case.pp
Notice: Compiled catalog for rcudb.example.com in environment production in 0.06 seconds
Notice: /Stage[main]/Main/File[/a]/seltype: seltype changed 'etc_runtime_t' to 'default_t'
Notice: /Stage[main]/Main/File[/a/a.a]/ensure: defined content as '{md5}d41d8cd98f00b204e9800998ecf8427e'
