Non descriptive error message when removing userdata

[TadiosAbebe]

When trying to remove userdata cloudstack UI reports an error

Request failed. (530) Internal error executing command, please contact your system administrator

Looking into cloudstack management server log the actual error was

20:12:07.329 2025-03-11 17:12:07,329 ERROR [c.c.a.ApiServer] (qtp1438988851-29131:[ctx-45557b51, ctx-ec1e932e]) (logid:90740b41) unhandled exception executing api command: [Ljava.lang.String;@5da3dc53 com.cloud.utils.exception.CloudRuntimeException: Userdata myser2 cannot be removed as it is being used by some VMs

It would be helpful to display a descriptive error message as an improvement.

This error appears when the operation is performed by a regular user on CloudStack, For root admins - a detailed error appears. This is done to avoid exposing underlying information to users.

@Pearl1594 , Thank you for the response.
But on a similar not is it normal that on the userdata pages, the View Instance button list all instances, whether they are using that userdata or not. Or am i missing something here?

@TadiosAbebe You're right, the listVms API doesn't correctly list VMs only associated to a particular userdata. I've created a fix: #10569 . It should be available in the upcoming 4.20.1 release. Thanks for identifying it.

Awesome, Thank you.
