Permission Denied mkdir()

[mbuechner]

There are tons of warnings because Drupal is not able to create a directory. I don't know what's going on and logging is not very helpful 'mkdir(): Permis...', '/var/www/html/w...',. Has something to do with Twig. Do you have any ideas where Drupal likes to add a folder, @Snater ?

What is the way to reproduce this? As to the stack trace this seems to be related to the BigPipe module.

@mbuechner Found the strack trace on https://community.bitnami.com/t/getting-error-user-warning-mkdir-permission-denied-in-drupal/59772 where it seems to have been tracked down to a ownership issue. Could you please check?

I don't know. Just read that in the logs. Looks like the error is gone away. I don't know.

Set chown -R www-data:www-data /var/www/html/web/sites/default/files again.
