  [ErrorException]                       
  Warning: sprintf(): Too few arguments  
                                         

Exception trace:
  at ./vendor/symfony/dependency-injection/Loader/YamlFileLoader.php:685

throw new InvalidArgumentException(sprintf('The file "%s" does not contain valid YAML: '.$e->getMessage(), $file), 0, $e);

Problaby because in my case the embedded $e->getMessage() also contains a %.

It seems this was already fixed in #36501 which will be part of the next tag.
