          Description

          Hi Fiware Team,

          I'm new to Fiware and working on some Fiware GEs.

          I wanted to test below scenario so I built an environment:

          [data]---->[Fiware-Orion]------------>[Nifi-Draco]--------->[Postgres]

          But during the execution I am facing below error in Nifi-draco. This seems as something wrong is sent to Nifi.
          Error: 2019-01-17 13:43:48,352 ERROR [Timer-Driven Process Thread-10] o.a.n.processors.ngsi.NGSIToPostgreSQL NGSIToPostgreSQL[id=66b53288-99b3-310f-c0d9-6e8046ba425b] java.lang.NullPointerException

          Request you to please help me out as I am stuck in the scenario.

            Hi Anurag,

            Please can you tell me what are the attributes that the ListenHTTP processor are receiving?. You can check that sending one notification and then, select the ListenHTTP Processor, do right click and select data provenance, then clink on the icon placed on the upper- left of the window and then click in the attributes tab, capture the screen and show me the content for checking what headers are you receiving.

            Best Regards,
            Andrés
