Unable to access FO environment during Debug

(1) ShareShare
ReportReport
Posted on by akshi 152
Hello,
 
I'm using a cloud hosted environment. When debugging, the following error occurs and the FO environment cannot be accessed.
When I set the created form as Start up object and press Start, the following error occurs and I cannot access the environment.
Could you please give me some advice on how can I access to the FO environment during Debug?

    Does it start working again you detach the debugger? Or doesn't did it crashed? Don't you see any error in Visual Studio? What about the SystemRuntime event log?

    Hello Martin,
    Thanks for confirm.
    Yes, It's working except debugger. There is no error in Visual Studio.

    Hi Akshi,
     
    1. Try restarting the VM and it should fix the issue
    2. If not then instead of setting the Form as Start up object, set the Display Menu Item corresponding to the form as Start up object
    2. If that doesn't work, then check the Detail section of Task Manager whether iisexpress.exe is running
    3. Restart World Wide Web Publishing Service
    4. Right click on the Form and click on View Code (F7) and set the break point (F9)
    5. Attach to process iisexpress.exe
    6. Open the F&O application URL. Hope this time it should hit the breakpoint and you should be able to debug.

    Hi,
     
    Does the form has any customizations that might be causing an issue? Maybe u can try to put a runnable class as a start object instead as a test.
     
    I would also advice to first build your model with sync then try again. 
     
    Thanks,
