Puppet 8x compatibility

[flepoutre]

Hi,
Would it be possible to make the module compatible with Puppet 8x ?

For example, currently :

Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Unknown variable: '::operatingsystem'. (file: /etc/puppetlabs/code/environments/flp_puppet8/modules/influxdb/manifests/params.pp, line: 37, column: 8) on node cladev-ubu2004.adm.fr.clara.net
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run


Thanks.
