title: Firebase Storage Upload Error: FIRStorageErrorDomain Code=-13000
body: <p>I am trying to upload an image to Firebase and I actually succeeded several times yesterday, but today I'm getting this error:</p>
  
  <blockquote>
    <p>Optional
      - Some : Error Domain=FIRStorageErrorDomain Code=-13000 "An unknown error occurred, please check the server response." UserInfo={ResponseErrorDomain=FIRStorageErrorDomain, object=ProfileImages/ascascasc ascas.jpg, error_name=ERROR_USER_NOT_FOUND, bucket=ichallenge-c52ae.appspot.com, ResponseErrorCode=-13020, NSLocalizedDescription=An unknown error occurred, please check the server response.}</p>
  </blockquote>
  
  <p>I want to reiterate: nothing was changed in the code between yesterday and today, it just stopped working. This is the code, I've highlighted the line where it happens with a comment:</p>
  
  <pre><code>@IBAction func signUpButtonPressed(sender: AnyObject)
  {
      // If textfields have more than 3 characters
      if firstNameTextField.text!.characters.count &gt; 3 &amp;&amp; passwordTextField.text!.characters.count &gt; 3 &amp;&amp; emailTextField.text!.containsString("@")
      {
          createUser()
  
          //Goes to Main Storyboard
          parseOutdated.signUpInBackgroundWithBlock { (success: Bool, error: NSError?) in
              NSNotificationCenter.defaultCenter().postNotificationName("Login", object: nil)
  
          }
      }
      else
      {
          firstNameShake.shakeAnimation()
          lastNameShake.shakeAnimation()
          passwordShake.shakeAnimation()
          emailShake.shakeAnimation()
      }
  }
  
  func createUser()
  {
      //Unwrap optionals before pushing to Firebase Database
      let name: String = "\(self.firstNameTextField.text!) \(self.lastNameTextField.text!)"
  
      storeProfileImage(name)
  }
  
  func storeProfileImage(name: String)
  {
      let profileImageData = UIImageJPEGRepresentation(self.profileImageView.image!, 1.0)
  
      // Create a reference to the file you want to upload
      let profileImageRef = storageRef.child("ProfileImages/\(name).jpg")
  
      // Upload the file to the path defined above
      profileImageRef.putData(profileImageData!, metadata: nil) { metadata, error in
          if (error != nil) //ERROR HAPPENS HERE
          {
              print("Image not stored: ", error?.localizedDescription)
          }
          else
          {
              //Stores the profile image URL and sends it to the next function
              let downloadURL = metadata!.downloadURL()
              self.storeUserData(name, profileImageURL: downloadURL!)
          }
      }
  }

  <p>Any help provided would be deeply appreciated.</p>
