Do you have a link to a good walk through on how to set up the proxy by any chance?

I used the steps suggested by ESRI which can be accessed here: http://help.arcgis.com/en/webapi/javascript/arcgis/jshelp/ags_proxy.html. Make sure that you add the serverUrls in the proxy file as mentioned in this document. I hope this is helpful.

I resolved my problem by focusing on my proxy page. It turned out that my proxy page was not working. I followed the instructions to set this up and I could see my proxy doing its job.

I have the same issue with my application. It was running fine all this while but this error message start appearing since last week. I have checked my code but cannot find any reason for this to happen. Interestingly, in my case the error message appears at the initial load. My dynamic combobox is not populated and some of my functions such as zoom etc. do not work. Refreshing the app takes care of these issues, but another refresh gives the same error message. So every alternate refresh gives the error message. Also, when this error message appears, my functions run only when I click the relevant button twice.

This is quite a general overview as it'll be hard to share my entire code to figure out where the problem lies. If too many people are facing this issue, then maybe ESRI should look into it from there end.

Thanks
Samir

Please provide more information on what you trying to do to encounter this error. I am guessing you are using Printing tools or Geometry service. This error usually comes up when you pass in the required parameters.
