Internal Server Error When Accessing Visible Columns in Devices Table

Question

I’m running into an issue with Headwind MDM where accessing or modifying the visible columns in the Devices table triggers an Internal Server Error. The rest of the interface works fine—only this specific feature seems broken.

 I am migrating Headwind deployment from Proxmox > VM to Kubernets 
 

What I’ve tried:

• Checked logs for stack traces

• Cleared browser cache and tried incognito

• Restarted backend services

• Verified database connection and schema integrity
  
  Thanks in advance!

When you're getting an Internal Server Error, check the Tomcat log (/var/lib/tomcat9/logs/catalina.out) for the exact error reason, in most cases the log will contain the error reason and the stack trace.
