When I am running drush image:flush --all. We are receiving below errors;
[warning] Undefined array key 2 LibraryStream.php:36
[warning] The following theme is missing from the file system: styles ExtensionPathResolver.php:63
[warning] The following theme is missing from the file system: styles ExtensionPathResolver.php:63
[warning] Array to string conversion LocalStream.php:122
I found web/modules/contrib/patternkit/src/StreamWrapper/LibraryStream.php file is causing this warning message. This below line of code is expecting the $uri should contain minimum two "/" however it received one "/" for which it's triggering these warning messages.
[$extension, $library, $type_level] = explode('/', $uri);
