[Developers] mql write bug help

[James Taylor]

Hello, I'm stumped on a bug and am hoping some alternate eyes can help.

I'm http posting mql writes to add data to freebase.  Most write queries are
working well, but this one seems to give me an error that I cannot reproduce
using the freebase query editor. It's likely a small error, but I can't seem
to find what's wrong. My post is:

{
        "q1": {
                "query": {
                        "id":"/guid/9202a8c04000641f800000000b0b99f0",
                        "type":"/location/mailing_address",
                        "street_address" : {
                                "connect" : "replace",
                                "value" : "test value",
                                "type" : "/type/text",
                    "lang":"/lang/en"
                                },
                        }
                }
}

And my errory response is:

mqlwrite response:
{
  "code": "api status error",
  "messages": [
    "JSON parsing error at line 1, column 252 (position 251): Unexpected
U+007D while looking for property name."
  ],
  "status": "500 Internal Server Error",
  "transaction_id":
"cache;cache02.sandbox.sjc1:8101;2009-03-01T02:34:00Z;0001"
}

And please find http info below.  However f I do the similar query in the
freebase query editor (http://sandbox.freebase.com/tools/queryeditor), it
works fine:
Querry:
{
  "id" : "/guid/9202a8c04000641f800000000b0b99e0",
  "street_address" : {
    "connect" : "replace",
    "lang" : "/lang/en",
    "type" : "/type/text",
    "value" : "12341234"
  },
  "type" : "/location/mailing_address"
}
Response:
{
  "id" : "/guid/9202a8c04000641f800000000b0b99f0",
  "street_address" : {
    "connect" : "present",
    "lang" : "/lang/en",
    "type" : "/type/text",
    "value" : "test value"
  },
  "type" : "/location/mailing_address"
}

Does anyone see where my error is?
Thanks much! -JT
