What is the problem in this code

    Dim JSON As JSONGenerator
    Dim m As Map = CreateMap("email":Email,"password":Password,"returnSecureToken":True)
    JSON.Initialize(m)
      Dim data As String =   JSON.ToPrettyString(1)
    Log(data)
    Log(Email)
    Log(Password)
    job.Initialize("job",Me)
    Dim link As String ="https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?key=XXXXXXXX-XXXXXXXXXXXXXXXXX"
    str = job.PostString(link,data)
'       job.GetRequest.SetContentType("application/json")
   job.GetRequest.SetHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:25.0) Gecko/20100101 Firefox/25.0")
    Log ("str:= " & str)
    If issingUp Then
    ToastMessageShow(str,True)
    End If

Setting the content type is a good thing.
I guess that the json payload itself is wrong.
