Ignition 8.0.16 - warning Tried to unregister a path/listener combination that is not present in the model

Hi in the gateway logs, if you hover over the magnifying glass to the right, it should tell you which project, view, component, and property that this error is coming from. I’ve seen this error occur when a expression binding references the same tag path more than once e.g. {tagA} + {tagA}. Therefore if you can restructure your expression to contain only one reference of the tag path, then the error would go away.
