The datastructure returned by fromJson is not known to Appian. To access these kinds of unstructured data you have to build a small expression to access data deeper down in the structure. Something like GetStepsFromStructure(local!test.data). Inside this expression you sould be able to use ri!data.steps or index(ri!data, "steps", {})
