find returns code 1

Trying to make it work on Puppet4. I changed $keymaster_storage and surrounded the mode in keymaster.pp by quotes, next problem is this, however:

2017-06-01 10:33:47,303 ERROR [qtp1637291203-71] [puppetserver] Puppet Server Error: Evaluation Error: Error while evaluating a Resource Statement, Evaluation Error: Error while evaluating a Function Call, Failed to execute generator /usr/bin/find: Execution of '/usr/bin/find /opt/puppetlabs/puppet/cache/username@park/key ! -newermt ' returned 1: /usr/bin/find: `/opt/puppetlabs/puppet/cache/username@park/key': No such file or directory at /etc/puppetlabs/code/environments/test/modules/sshkeys/manifests/setup_key_master.pp:49:10 at /etc/puppetlabs/code/environments/test/modules/sshkeys/manifests/create_key.pp:21 on node fourstrings.vub.ac.be

the problem is that the key does not yet exists, has not been generated, and therefor the directory /opt/puppetlabs/puppet/cache/username@park/ has not yet been created.
