Description

Multiple components contain string definitions of the following FlowFile Media Types:

• application/flowfile-v3
• application/flowfile-v2
• application/flowfile-v1

The ListenHTTP and PostHTTP processors also define the following FlowFile Media Type without a version number:

• application/flowfile

These string references should be replaced with a standard enumeration that can be used across components and unit tests.
