001376 : Output parameter <value> in task <value> requires a result map service.

Description

The geoprocessing service you are creating uses an unsupported output data format. The result of your service can only be returned as an image by using a result map service.

Solution

You need to enable a result map service from the Parameters page of the Service Editor.

Note:

A result map service requires the output to be written to disk (not to the in_memory workspace) and the service set to asynchronous execution.
