We’ve been getting this log error (technically debug status, logger com.inductiveautomation.ignition.common.expressions.JsonGet). The text quoted above is the entire message, and there is the text ‘java.lang.NullPointerException: null’ when I hit the expand button in the log page on the gateway. In the last 24 hours, there have been about 20 million instances of this over 3 gateways. Not all of our gateways get this either, one of them got about 50 million in one day and then… nothing more.
We use plenty of derived tags so I’m guessing it has something to do with those, but I’m not sure how to find where its coming from because there is just soooo little information in the error. I’m looking for any suggestions to help where this is coming from so we can fix it. I know it isn’t really a huge deal since its a debug log, but if it could point to something else bigger then I’d like to figure out whats going on.
