Adding on, 'RouteOnAttribute' takes ExpressionLanguage. "*$.result.status*"
is not an ExpressionLanguage (EL) but a JSON Path expression. So what you
can do is, use EvaluateJsonPath processor to read the value of status using
"$.result.status" and assign it to an attribute, say "statusField" (this
gets added as a FlowFile attribute). Connect EvaluateJsonPath with
RouteOnAttribute and reference the attribute you have added in
EvaluateJsonPath using EL. Ex: ${statusField:equals("OK")}On Mon, Oct 15, 2018 at 6:31 PM Sivaprasanna <sivaprasanna...@gmail.com> wrote: > Vyshali, > > UpdateAttribute adds an attribute to the FlowFile i.e. just like filename, > filesize, etc., when you set "status" : "OK" using UpdateAttribute, the > field doesn't actually get added to the JSON content.
