Parameter error when submitting feedback

Problem description

A parameter error occurs when you submit feedback:

Problem analysis

This error usually occurs because the AppKey and AppSecret parameters are incorrect.

Solution

• Verify the values by comparing them with your server-side data. For example, the AppKey or AppSecret in your project might not match the one in the console.

• If the values are correct, check for memory issues. The network request might not be sent to the server-side if the YWFeedbackKit object is released prematurely.

• For Android, upgrade to version 3.3.1 and test the feedback submission again.

The following example illustrates the second scenario.

A user might open the feedback page with the following code:

 - (void)viewDidLoad {
    [super viewDidLoad];
    FeedbackHelper *helper = [FeedbackHelper new];
    [helper openFeedbackViewController];  
}

The FeedbackHelper contains the following logic:

 @interface FeedbackHelper ()<UISplitViewControllerDelegate>
@property (nonatomic, strong) YWFeedbackKit *feedbackKit;
@end


- (YWFeedbackKit *)feedbackKit {
    if (!_feedbackKit) {
        _feedbackKit = [[YWFeedbackKit alloc] initWithAppKey:kAppKey appSecret:kAppSecret];
    }
    return _feedbackKit;
}

/** Opens the user feedback page */
- (void)openFeedbackViewController {
    [self.feedbackKit makeFeedbackViewControllerWithCompletionBlock:^(YWFeedbackViewController *viewController, NSError *error) {
        if (viewController != nil) {
            UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:viewController];
            [ [ViewController getInstance] presentViewController:nav animated:YES completion:nil];

            [viewController setCloseBlock:^(UIViewController *aParentController){
                [aParentController dismissViewControllerAnimated:YES completion:nil];
            }];
        } else {
            /** Comment out this section if you use a custom method to throw the error. */
            NSString *title = [error.userInfo objectForKey:@"msg"]?:@"The API call failed. Please ensure your network connection is stable.";
            NSLog(@"%@", title);
        }
    }];

}

When the page opens, the helper object is released, which also releases the self.feedbackKit object. As a result, the AppKey and AppSecret properties are also released, causing a parameter error when the network request is sent.

Change the setting to the following:

    FeedbackHelper *helper = [FeedbackHelper sharedInstance];
    [helper openFeedbackViewController];

Alternatively, set FeedbackHelper *helper as a property:

@interface ViewController ()
@property (nonatomic, strong) FeedbackHelper *helper;
@end

 - (void)viewDidLoad {
    [super viewDidLoad];
    self.helper = [FeedbackHelper new];
    [helper openFeedbackViewController];  
}

This prevents the FeedbackKit object from being released, which ensures that the AppKey and AppSecret values are not released from memory prematurely. As a result, subsequent network requests do not cause parameter errors.
