It seems like there might be an issue with the visibility of your external function in the web service. Ensure that the file containing the function definition is properly included or required in the service where you expect it to be available. Additionally, double-check the class name ('local_sociogram\external\get_graphs') and the function name ('local_sociogram_get_graphs') for consistency.
Confirm that the necessary file is loaded and that there are no typos or errors in the declaration. If the problem persists, consider checking the logs for any error messages or debugging information that could provide insight into why the function is not appearing as expected in the service.
