I upgraded my Cirrus Link MQTT modules. Afterwards, everything seems okay, but I can't navigate to the servers page in the Engine settings. I've tried rebooting gateway and reinstalling the module, but I still get an "Internal Error" in the webpage. ```python org.apache.wicket.WicketRuntimeException: Error attaching this container for

I just found this thread, and am going to try their solution.

How do I edit the internal db? The problem is obviously here ```python [EngineServerSetRecord 0 NewRecord] ``` ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/a/4/a40448482aa23578255e6f213a7098cdb6c33af9.png) ---

The only way I know of to access it is through the gateway web interface, but I haven't looked at it in a long time, so I'm not sure it still works that way. The URL has to be typed in manually: ```python .../web/status/sys.internaldb ``` The fact that it's access is intentionally obfuscated is an indication that it probably shouldn't be done without involving support. ---

You are correct, I was able to clear my EngineServerSetRecord table using that page with the help of support.
