ArcGIS Pro: 3.0.3
ArcGIS Enterprise Server (Linux): 10.9.1
I followed the following tutorials to create a custom print service so we can utilize additional templates for printing web maps.

However, the export fails every time and we receive the following error. Error executing tool. Export Web Map : ERROR 000800: The value is not a member of MAP_ONLY.
As you can see, the Layout_Template parameter contains an array with two values: Layout and MAP_ONLY. I've published the ExportWebMap service with both MAP_ONLY and Layout as the default value, but haven't had any luck.

Has anybody experienced this issue? It has been such a pain getting custom print templates to work with our web maps on Portal!
