Invalid type for key fileType, expected bytes, but got string

Hi,

I am trying to display my messages in the InboxViewController but I get a runtime error because the fileType is null. On checking the data browser on Parse it seems the fileType is not getting saved when I send the messages in the CameraViewController. The error that i get in the debugger is - "Invalid type for key fileType, expected bytes, but got string " i.e. the variable fileType which is NSString cannot be saved using the message setObject forKey method of PFObject. I did not find any notes in the bottom of the video. Is it something to do with the new version of xcode? I am really stuck here and though I have a workaround for now, I want to know whats happening :(

Thanks!

can you post your code where you set the value of the file type?

PFObject *message = [PFObject objectWithClassName:@"Messages"];
            [message setObject:file forKey:@"file"];
            [message setObject:fileType forKey:@"fileType"];
            [message setObject:self.recipients forKey:@"recipientIds"];
            [message setObject:[[PFUser currentUser] objectId] forKey:@"senderId"];
            [message setObject:[[PFUser currentUser] username] forKey:@"senderName"];
            [message saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {

}

can you post the code where you set the file type variable thats used in this line?

 [message setObject:fileType forKey:@"fileType"];

where did you set that fileType variable?

Make sure for your fileType variable you declared it as NSString *fileType and not PFFile *fileType

It is NSString. I double checked!

 NSString *fileType;

    if(self.image != nil){
        UIImage *newImage = [self resizeImage:self.image toWidth:128.0f andHeight:128.0f];
        fileData = UIImagePNGRepresentation(newImage);
        fileName = @"image.png";
        fileType = @"image";
    }else{
        fileData = [NSData dataWithContentsOfFile:self.videoFilePath];
        fileName = @"video.mov";
        fileType = @"video";
    }

Is it something to do with the Parse API? The workaround was to drop the class from the data browser and again run it. That worked! No change in code!
