Would be great to pick a "mode", if you run a task as a "EasyMorph Server command" to have the chance to return a table - similar to "call another module/project" action, where you can select a project (not published on the server)
Server tasks by their purpose are not expected to have a result, however you have a point. A Catalog asset (e.g. computed dataset) is effectively a task with a result. As of today, you can use the "Retrieve from Catalog" action to perform a calculation (with a workflow) and obtain the result (see below).
In the future, we're considering making it possible to use projects published to Server in the "Call" and "Iterate" actions as if it can already be done with local projects.
Looking forward to this option!
