Jenkins ver. 2.222.3
Configuration as Code Plugin 1.40
LogFileFilter Plugin 1.11
After starting a Jenkins instance with a simple configuration, Jenkins throws NPE when trying to filter lines. Of note, I'm using the plugin from a Jenkins Shared library within in a declarative pipeline.
There is a very simple workaround under "Configure System"
1. Un-check the "Enable Gobally" box under the plugin configuration
2. Click Apply
3. Re-check "Enable Globally"
4. Click Apply
After this, no more NPE's are thrown.
