I have a Slate app in Foundry and in there we have a dialogue using the action widget to enable the user to enter data.

So far, we created the action inside of the object and all backing datasets exists.

However when testing the new dialogue it still says:

One of the resources that you are trying to modify has not been initialized yet. Please retry later.

Any idea? Waiting is no solution, the issue is now shown for several hours…

This usually means that the object type that is being edited by the action has not been initialized in the ontology yet. As a first pass, I’d check the objects being modified in OMA(specifically the datasource tab) to see if anything is wrong.
