[jira] [Commented] (FLINK-34066) LagFunction throw NPE when input argument are not null

    [ https://issues.apache.org/jira/browse/FLINK-34066?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17805925#comment-17805925 ] 

Martijn Visser commented on FLINK-34066:
----------------------------------------

Can you please elaborate a bit more and have a reproducer? What I'm seeing in the PR is that you're just adjusting the test so that we don't test with NULL anymore, but I don't see an explainer why we don't want to test for that anymore.
