xtrabackup

[ubellavance]

Describe the Bug

Error when running puppet with an xtrabackup config created. Error: Evaluation Error: Error while evaluating a Function Call, 'versioncmp' parameter 'a' expects a String value, got Undef (file: /etc/puppetlabs/code/environments/production/modules/mysql/manifests/backup/xtrabackup.pp, line: 53, column: 8)

Expected Behavior

puppet apply should run w/o error

Steps to Reproduce

Steps to reproduce the behavior:

1. Manifest to get configuration from hiera:

  # Create backup configuration in Hiera
  if $mysql_backup_config {
    # Using create_resources
    # create_resources('class', $mysql_backup_config, {})
    # or
    # using each(preferable)
    $mysql_backup_config.each |$backup_class,$backup_config| {
      class { $backup_class:
        * => $backup_config,
      }
    }
  }

2. Hiera configuration :

profile::mariadb::mysql_backup_config:
  'mysql::backup::xtrabackup':
    backupuser: 'backupuser'
    backuppassword: 'blabla'
    backupmethod: 'mariabackup'
    backupmethod_package: 'mariadb-backup'
    backupdir: '/var/backups/mysql/'
    backuprotate: 7
    execpath: '/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin'
    time: [ '23' , '15' ]

Environment

• Puppet 7.25
• RHEL8

Additional Context

If I remove the xtrabackup config above, puppet runs OK. Once MariaDB is installed, I can re-instate my xtrabackup config and it runs OK.
