The result map service used to draw the results of a task requires output to be written to disk. It cannot be written to memory.
You must either disable the result map service for the service you are creating or modify the output to be written to disk. If your workflow requires a result map service, follow these steps to modify your workflow:
- Remove the task from the Service Editor.
- Open the model or script tool from which you are building your task.
- Modify the final output parameter to write to disk (instead of in_memory) and run your tool.
- In the Service Editor, click the Add Result button to select your most recent result.
