In my case the json file encoding was a problem  I was generating JSON file in vb  net with following  My Computer FileSystem WriteAllText  newComponent json   json Trim  False   And I tried all suggestions in this post but none helped   Eventually in Notepad   noticed that the file created was in UTF-8-BOM  Not sure how it picked up that encoding but after I switched the encoding to UTF-8  it resolved with no other changes   Hope this helps someone
