invalid key name: _noBody

[ngjohn]

Hi,

I create an ParseObject in client side,
then, try to update the record using below code.

    ParseObject     record = ParseObject.CreateWithoutData("LockRecord", objectID);
    record.Increment("lock_count");
    Task run_task =   record.SaveAsync();

..

if(run_task.IsCanceled || run_task.IsFaulted)
{
// fail.....
}

the saveAsync() failed....

when I print out the exception msg, it said "invalid key name: _noBody"

this error happen after I host the server myself, it is not happened before~

Can someone give me some hints? Thanks a lot.

Can you check in your mongo database, do many of your LockRecord objects have a _noBody key on them?

[ngjohn]

Hi,

I just check the LockRecord table, no _noBody key was found~
they looks like this...

{
    "_id": "0OynPm0hnK",
    "attacker_id": "65lnd0hqMy",
    "defender_id": "zp2B6QvNuD",
    "lock_count": 3,
    "_created_at": {
        "$date": "2015-12-30T09:56:18.225Z"
    },
    "_updated_at": {
        "$date": "2015-12-30T10:01:47.704Z"
    }
}

For your information, this database is migrated from my existing Parse's DB. using the 'migrate' button...
after migration, i found lot of strange Collection such as _dummy, _Index, _EventDimension....

this problem is the first-time happened to me (after self-host), and I am new to mongodb)
I really dun know what is the reason~

Also, the SaveAsync() fail issues happened on ParseUser as well, when I try to update a _User field from the client code.

Thanks.

Ok, looks like the dot net SDK sets this field and we're choking on it... https://github.com/ParsePlatform/Parse-SDK-dotNET/search?utf8=%E2%9C%93&q=_noBody

Valid bug, will work on a PR.

Hi,

I just updated the parse-server to v2.1.0,
and I run a test on [Unity] the SaveAsync()... I got the same _noBody result.
do i miss something? or other package I need to update as well...?

I confirmed that the parse-server is v2.1.0.
and node is v4.3

Thanks a lot.

No, 2.1.0 was supposed to supposed to fix this issue. We'll take a look. If you want to help, you could submit a PR that includes a failing test case :)

[ngjohn]

Hi, gross,

I do want to help, can I submit a PR with code snippet in c# ? because I am developing on Unity c# .

currently, I am quite sure that this is ONLY happened in Unity ( Not in VS dotNet project)

:)

[drew-gross]

Currently our test setup is only JavaScript, sorry :( the Unity SDK is the only one uses the _noBody key so it would be the only one that fails. If you don't want to write JavaScript, another way to help would be to capture a failing network request as a CURL command (or similar) and post that here. Unfortunately I don't know how to do that in Unity, but I searched for some tools, it seems like this one might help: http://www.telerik.com/fiddler

If the previous fix didn't work (removing _noBody from the request.body,) it's possible that this option is being passed as the request.query string... If you add some a console.log statement to print these out and make a few requests, you might be able to pinpoint the issue.

[ngjohn]

HI,
I try to remove the _noBody, and confirmed it is Ok ( I just make several create, update , query request to the server...)

 var parsed = Json.Parse(t.Result) as IDictionary<string, object>;
          // Inject the method
          parsed["_method"] = httpRequest.Method;
          //parsed["_noBody"] = noBody;    // fix _noBody bug.....( #448 )
          bytes = UTF8Encoding.UTF8.GetBytes(Json.Encode(parsed));

https://github.com/ParsePlatform/Parse-SDK-dotNET/search?utf8=%E2%9C%93&q=_noBody

I will keep checking for any side-effect of removing the _noBody key.

Hope this help some other Unity developer.

@gfosco this is actually for non POST methods: https://github.com/ParsePlatform/Parse-SDK-dotNET/blob/f577ee38a0d55a199a473065b18acad084e4b083/ParseCommon/Internal/HttpClient/Unity/HttpClient.Unity.cs#L43

if (!httpRequest.Method.Equals("POST") || httpRequest.Data == null) { 

[ngjohn]

Yes, I found that 'update' & 'delete' object will use PUT methods....
and this will inject a '_noBody' in the request.

Assuming that #512 corrected things in 2.1.3. Please re-open if not.
