I never use grokdebug.herokuapp.com or other grok debuggers (including kibana) because they sometimes interpret ambiguous regexps differently to grok. And many regexps that use DATA, or especially GREEDYDATA, are ambiguous. The process I suggest to develop complex grok patterns is documented here.
Please edit your post, select the log file entries and click on </> in the toolbar above the edit pane. In the preview pane you will see the display change to
at java.util.regex.Matcher.appendReplacement(Matcher.java:880)
at java.util.regex.Matcher.replaceAll(Matcher.java:955)
at java.lang.String.replaceAll(String.java:2223)
Then do the same for the configuration. Please do not do it to the whole post.
