   Instead of relying on a parameter context for the output bucket we could add a property on the processor.
   For that property and the incoming flowfile attributes we could build a custom map and add that as parameter to the `evaluateAttributeExpression` call when getting the value of the payload JSON.
   When both the property and a similar flowfile attribute is set, flowfile attributes should have precedence.
   
   Also the type of Vision action (like `DOCUMENT_TEXT_DETECTION`) could come from a property as well.
