2. As Node.js was configured in my environment , I just thought of testing using that and I added the localhost:8765 in Tableaufans-WriteBack-2018.2.trex file. When I run the npm start, I am able to see the write back extension, but when I click on “Pipeline” as sheet to choose data selection, “POST /Tableaufans-WriteBack-2018.2/php/writeToDb.php” Error (404): “Not found”is the error prompted in the command prompt.
