Hey Karthik,
Not exactly, the schema that would cause issues would be [CHOICE[STRING,
ARRAY[STRING]]. This would result in a valid test case that is either:
[{"path": "10.2.1.3"}] or [{"path": ["10.2.1.3"]}]. I'm having trouble with my
build environment attempting to test master (Intellij says: "Error:java:
invalid source release: 11") so I can't test it at the moment but the code does
look like it has changed since this was first created if the test case works if
you change it as listed in the description then I'd consider this OBE.

Hi Joe,
I was trying to reproduce the same error in testChoiceArray() class. Could you
please tell me, if for example the schema was of the form [STRING,
CHOICE[ARRAY[STRING]]] which according to the testclass should have produced
[\{"name":"John Doe","path":["10.2.1.3"]}].
are you getting the issue while doing this?

Joseph Percivall commented on NIFI-5775:
[~sivaprasanna] this can be replicated in the unit tests by adding the String
data type to the linked unit test.
To be more exact on when it'll occur, if you have a field with the ability to
be multiple types (e.g. array + string + null) and have string as first in the
schema type list, this will occur.
