Description

I noticed that getSystemUpdateState requests remain unresponded in my local OpenEMS test system.

I analyzed and found that the following code

calls an exception handler without providing an exception (ex == null).

I added a proper IOException. This resolves the issue and the requests are properly responded (with an error response)

Screenshots

No response

Operating System

Ubuntu 24.04

How to reproduce the Error?

Navigate in the WebUI to settings -> systems.

Trace the websocket communication in the browser console.
