I am trying to print a map that I made with arcgis server 10.2 and arcgis javascript api.
The problem is that I keep getting an error (code: 400, message: "Unable to complete operation.", details: Array[1], log: undefined, httpCode: 400).
which is more specifically -->
Unable to complete operation.
Error executing tool.: Layer "graphicsLayer8": Failed to create layer from service at http://MYSERVER/arcgis/rest/services/Tests/MyFirstMapService/MapServer/2. Layer "graphicsLayer9": Failed to create layer from service at http://MYSERVER/arcgis/rest/services/Tests/MyFirstMapService/MapServer/2. Layer "graphicsLayer10": Failed to create layer from service at http://MYSERVER/arcgis/rest/services/Tests/MyFirstMapService/MapServer/0
