Facter / FACT-3036 Null value custom facts don't load Issue Type: Bug Affects Versions: FACT 4.0.44 Assignee: Unassigned Components: Facter 4 Created: 2021/05/10 11:35 AM Environment: I'm running Centos 7 with Puppet 7.6.1-1. Fix Versions: FACT 3.y Priority: Normal Reporter: Brian Gibson In Facter 3, if I have a custom fact, a simple one in a txt file in /etc/puppetlabs/facter/facts.d/ where the variable = null, it will show up in facts, and I can use it in my code checking for the null value.  In Facter 4, the variable doesn't load at all.

Re: Null value custom facts don't load Hi Brian Gibson I've tried to reproduce the issue with the following file, but I can access the fact:     ❯ cat /etc/puppetlabs/facter/facts.d/test.txt var=null ❯ /opt/puppetlabs/puppet/bin/facter --version 4.1.1 ❯ /opt/puppetlabs/puppet/bin/facter var null ❯ puppet apply -e 'notice($facts["var"])' Notice: Scope(Class[main]): null     Can you provide a bit more of details?

Re: Null value custom facts don't load

Okay I see that behavior as well, the problem I'm having results from accessing information from puppetdb specifically. On my puppet master server I have the following versions: puppetserver 6.15.3 puppetdb 6.16.1   We're using a python script against puppetdb.  When we have facts that are set with a null value, with puppet agent 6.22.1 they show  up in puppetdb also with the null value, but when my puppet agents were upgraded to version 7 my facts with null values no longer populate in puppetdb.

I've upgraded to the latest puppet/server/pdb and I can see the fact. ❯ curl -X GET http://localhost:8080/pdb/query/v4/facts/var | jq .   [ { "certname": "my_host", "environment": "production", "name": "var", "value": "null" } ]

Re: Null value custom facts don't load bgibson710 have you been able to reproduce the error? Note I found some discrepancies between facter 3 and 4, see FACT-3111. Not sure it's related?

To be honest this has been so long ago I don't recall it anymore.  If others are saying that it's working as intended I guess just close it out.
