Warning: mkdir(): File exists in Drupal\Core\File\FileSystem->mkdirCall() (line 234 of core/lib/Drupal/Core/File/FileSystem.php).Drupal\Core\File\FileSystem->mkdirCal

Problem/Motivation

are are the permissions and mode for the advagg folder:
drwxrwxr-x 61 www-data www-data 4096 Jun 9 09:52
/my-path-to-tmp/site-name/advagg/

How do I suppress this as it already exists?

But if I refresh the directory is there.

I keep getting these warnings
