Hello @michal-cesek
thank you for raising this!

Currently we assume that value is a json (obj/string/integer). If value is not valid json ( like string 123notajson ) we set it to null. So, there can be 2 cases then value is null in filter:

• kafka-record's value is null
• kafka-record's value can't be represented as json after deserialization

This is why you see false-positive filters.

We will discuss it internally and think how to fix this. For now, as workaround you can use valueAsText variable in filter that will be null only if kafka-record's value is null.

@iliax thank you for taking care of this. In addition, I wanted to point out that there is inconsistency in the UI. The second screenshot shows an active filter and the search box input filled with the code -> Ok. The third screenshot shows the same active filter, but the search box is not prefilled -> Not Ok / Confusing
