Hi guys,I was just testing mendix 11.12 and after a while it started to show an error whenever I run locally the project (see below).It can run locally, but I'm unable to debug the project.Any thoughs?Mendix.Modeler.Utility.Network.ServiceResponseException: An error occurred while processing the response from the Debugger. ---> System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.Http.HttpIOException: The response ended prematurely.

Hi Andre,
This looks like a Studio Pro/Debugger communication issue rather than an issue with your application.
A few things I'd check:
Try Clean Deployment Directory and run the application again.
Verify that no firewall, proxy, or antivirus is blocking the local debugger connection.
Check if another process is already using the debugger/runtime port.
If the project runs normally but only debugging fails, try creating a new blank project in 11.12 and see if the debugger works there.
Since this started after upgrading to 11.12 and the application still runs locally, it could also be a regression in Studio Pro. If the issue is reproducible in a clean project, I'd recommend raising a Mendix Support ticket with the stack trace.
Kindly mark this as the accepted answer if it helps.
