If we are not mocking our connectors, on running munits mule 4 will actually connect post request to the external environment through connectors used in out project. Functions defined in Core (dw::Core) module are imported automatically into your DataWeave scripts. The example stores the current HTTP Attributes in a variable to make use of them later in the flow because the next operation will replace the current Message. It may consist of inbound Headers, Query Params, URI Params, HTTP method etc.In Mule Inbound properties are preset by the sender of the message thus cannot be added or modified.
