Assertion failure in -[GTMHTTPUploadFetcher connectionDidFinishLoading:]

Question

i am trying to upload a video on youtube using Google APIs Client Library for Objective-C, I using given below code but it is keep on giving me this error, i tried to run my account on youtube example project here again it gives that same error.

Can any one guide me where is the problem. I check YouTube Data API v3 is on in services page.

*** Assertion failure in -[GTMHTTPUploadFetcher connectionDidFinishLoading:], /Volumes/data/Work/test/DLNew/DL/google-api-objectivec-client-read-only/Source/HTTPFetcher/GTMHTTPUploadFetcher.m:399

i check the code of GTMHTTPUploadFetcher class it is crashing the app on this link

`#if DEBUG
  // The initial response of the resumable upload protocol should have an
  // empty body
  //
  // This assert typically happens because the upload create/edit link URL was
  // not supplied with the request, and the server is thus expecting a non-
  // resumable request/response.
  NSAssert([[self downloadedData] length] == 0,
                    @"unexpected response data (uploading to the wrong URL?)");
 #endif

The problem was i was logging from a new gmail account so i need to login in youtube site and need to create a channel before i can upload video to youtube. So now i can upload videos after creating a youtube channel. but How can i handle this scenario for other users, any idea

I encountered the same crash and find out a solution. It seems that the client gets this crash also if the underlying request is a bad request but no response information are explicitly provided (my authorizer is valid and passes the check with the method canAuthorize as Ryan_IRL pointed out).

After a look at the library I found out that setting the preprocessor macro STRIP_GTM_FETCH_LOGGING and enabling the logging for the HTTPFetcher somewhere in the code

#if STRIP_GTM_FETCH_LOGGING
[GTMHTTPFetcher setLoggingEnabled:YES];
#endif

the logs are stored in the GTMHTTPDebugLogs folder inside the Simulator (something similar to /Users/<username>/Library/Application Support/iPhone Simulator/6.1/Applications/65451CDB-27D6-4BE2-910C-7F22D6A01832/GTMHTTPDebugLogs). There you can find the complete log in HTML format (...).

Clicking on 'request/response log' the following log was shown in my case.

Response body: (201 bytes)
{
  "id" : "gtl_1",
  "error" : {
    "message" : "Bad Request",
    "code" : -32602,
    "data" : [
      {
        "domain" : "youtube.video",
        "reason" : "invalidTitle",
        "locationType" : "other",
        "location" : "body.snippet.title",
        "message" : "Bad Request"
      }
    ]
  }
}

the bad request was related to the title (of the video to be uploaded) that was containing some forbidden chars. Fixing the title solved the crash and the video was uploaded correctly. A status 200 in this case is of course... frustrating and clearly wrong.

I'm strongly disappointed also by GTM Library, and by the use of the NSAssert for such situation in the first place.

I had the same problem as you (assertion failure in GTMHTTPUploadFetcher.m:399) while uploading a video to YouTube. I'm posting this in the hopes of saving someone else a few minutes of debugging.

It turned out my problem was old code that set GTLServiceYouTube's APIKey, in addition to using OAuth2. Doh.

GTLServiceYouTube *youtube = [[GTLServiceYouTube alloc] init];
youtube.APIKey = @"-my-simple-api-access-key-"; //<-- offending line
[...]
youtube.authorizer = [GTMOAuth2ViewControllerTouch authForGoogleFromKeychainForName:kKeychainItemName
                                                                 clientID:kYouTubeClientID
                                                             clientSecret:kYouTubeClientSecret];

The fix was simply to leave APIKey nil, using only the OAuth2 authorizer. (APIKey is for 'Simple API Access' only, evidently, any hint of both leads to problems).

Fwiw, the http request succeeded (200 OK), but the http response told a different story. To view the response I added these two lines to the implementation of GTMHTTPUploadFetcher.m (perhaps theres a better way):

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
    [...]
    NSString *dataStr = [[NSString alloc] initWithData:self.downloadedData encoding:NSUTF8StringEncoding];
    NSLog(@"Downloaded data:%@",dataStr);
    [...]
}

The JSON in dataStr:

{
    "error": {
        "code": 403,
        "message": "Access Not Configured",
        "data": [{
            "domain": "usageLimits",
            "reason": "accessNotConfigured",
            "message": "Access Not Configured"
        }]
    },
    "id": "gtl_1"
}

Sorry if I'm making an assumption here, but I had the same error as you, and it turned out the issue was actually my authorizer. Make sure you are handling errors with auth, and are applying the auth to the service.authorizer.

if (![self.youTubeAuth canAuthorize]) {
    // ...
}
service.authorizer = auth;

I was also having this issue due to having the wrong scope for the GTMOAuth2ViewControllerTouch initializer. @"" will give you better results than the wrong scope. Check the YouTube example app.

Answer 5

I guess you need to enable Drive API and Drive SDK from the API services tab

Switch the services to on for the project and try again.

If Both are on then make sure you have set the "api_console_project_id" : "xxxxxxxxxxxxx" argument in your manifest.

I found it from here, google-youtube-api-v3-ios-app-key-403-error-code

Basically, it will work if we use a Key for browser apps instead of a Key for iOS apps.

Answer 7

Don't know if anybody already found the solution for this but here is what I implemented (in Swift) to avoid the app crash:

First check for the Youtube channel status using:

GTLQueryYouTube.queryForChannelsListWithPart with part set to "status"

If the value of "isLinked" parameter is not 0 in the response then only upload the video using

GTLQueryYouTube.queryForVideosInsertWithObject

otherwise ask user to link youtube channel first.

GTLServiceYouTube *youtube = [[GTLServiceYouTube alloc] init]; youtube.APIKey = @"-my-simple-api-access-key-"; //<-- offending line youtube.authorizer = [GTMOAuth2ViewControllerTouch authForGoogleFromKeychainForName:kKeychainItemName clientID:kYouTubeClientID clientSecret:kYouTubeClientSecret];
