Code

public function __construct(InvalidDataTypeException $exception) {
  $this->sourceLine = 1;

  // Attempt to extract the line number from the serializer error. This isn't
  // a very stable way to do this, however it is the only way given that
  // \Drupal\Component\Serialization\SerializationInterface does not have
  // methods for accessing this kind of information reliably.

      // Add any matching line count to the existing source line so it
      // increases it by 1 to account for the front matter separator (---).
      $this->sourceLine += (int) $matches[1];
    }
  }
