Thank you Mark for your for your reply.

According to the NIFI API documentation <http://nifi.apache.org/docs.html>,
parameter-contexts is for creating a new parameter context.

Yesterday, I blindly tried different "ParameterContextEntry" in the API but
failed to list all the parameter contexts. It can only create a new
Parameter Context and returns json with ID of the newly created parameter
context.

Thanks,
Bahlul
