There are two reasons which may cause this error in Javascript.

1. Path Setting Incorrect
2. Server Side Error



Path Setting Incorrect

In file "index.html", it defines server side file UserCommandProcessHandler.ashx location.



We will use these two values to get the server side file UserCommandProcessHandler.ashx location. "http://your-host:port/{_rootpath}{_serverUrl}"

To verify that you have setup remote file "UserCommandProcessHandler.ashx location" correctly, please open your web browser, and navigate to "http://your-host:port/{_rootpath}{_serverUrl}".

For example: "http:// localhost:9091//RasterEdge_Resource_Files/UserCommandProcessHandler.ashx"

If you have setup the values correct, you can see the following content in the web browser.

If you get a "404 error", your path setting is wrong.
