Hi Nitin, Thanks for your reply. It might not be a particular case. From soruce code, indeed, cloudstack map exception to errorcode, but the error message returned from UI/API is not fine-grained enough to help users narrow down the reason,
Now there are about 60 exceptions, which map to 60 errorcode. Does one exception always come up with the same error message (or message format), or it depends on the code which throws it? Regards Mice
