Error Details

This is indicates, mostly, that the data returns from the action, under data location/position, isn’t match Rivery expectations on how the datasets should return from an action river. Using action as source, Rivery assumes the data in data location key under the Results tab on the action river will be structured as [array] of {jsons}. However, in some cases, when the data comes as other types, like str(string), int (number), or dict(one or more jsons with no array…) only, the error above may be raised.
