System: NPM 12.0.0
Issue: When creating a new Universal Device Poller, when the "Browse MIB Tree" button is clicked, I get a pop-up that says "Object reference not set to an instance of an object." I also get this error if trying to edit an existing poller and click on the same button.
Question: Has anyone experienced this/know what to fix? In the past I've seen this same extremely clear error message in the web UI when editing resources and the fix is to clear some IIS caches and reinstall the web site. I haven't seen it affect browsing a MIB before.
Update: The only thing I've run across in the Customer Support Knowledge Base is a reference to just reinstalling/updating the MIB database as it was "corrupt". There were not references to my error, just "unable to browse the MIB database". I'm going to try that if no one speaks up in a few days. If there's a non-impacting thing I can check or do first I'd rather do that. MIB Db replacement causes an Orion outage to start/stop services.
