i have a attribute (that produced by a REST service and catched by invokeHTTP processor) in JSON format like this:
{code:java}
test => {"key":"value"}{code}
and then i want to put it in flows JSON content using JOLT processor, my content is something like this:
{code:java}
{ "id": 123, "user": "foo" }{code}
and my JOLT specification is this:
{code:java}
[{ "operation": "default", "spec": { "interest": "${test}" } }]{code}
the problem is here that, in JOLT advanced window with test attribute nifi cannot put json object and shown this error:
{quote}*"Error occurred during transformation"*
{quote}
and when run processor this detailed error is become alerted:
{quote}*"unable to unmarshal json to an object"*
{quote}
----
my desired result is this:
{code:java}
{ "id": 123, "user": "foo", "interest": {"key":"value"} }{code}
is this a bug or am i wrong?
