That wasn´t point of that remark. This "look into logs" assumes that I have
access to them which must not be true. But luckily I have it. Here it is:

> ExecuteSQLRecord chrashes if no resultset
> -----------------------------------------
>
> Key: NIFI-8014
> URL: https://issues.apache.org/jira/browse/NIFI-8014
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.12.1
> Reporter: Michal Šunka
> Priority: Major
>
> If in ExecuteSQLRecord I has code which does not return a resultset e.g.
>
> {code:java}
> DECLARE @a int
> SET @a = 1
> {code}
> It fails with NullPointerException.
>
> I cannot give You exact error string since it is not selectable (handy, isn´t
> it?)...
> And picture-upload as attachment fails with "Jira could not attach the file
> as there was a missing token. Please try attaching the file again." Repeated
> attempts, drag'n'drop nor browse does not work...
> !NiFi_NullPointerException.jpg!
