Symfony oneup league flysystem file not found - symfony

Question

I am uploading files using oneup/flysystem-bundle and vich/uploader-bundle and that works fine.
When trying to delete a file with
$this->filesystem->delete($path)
it throws error saying that file not found, although the path is correct.
This question suggests that this may be due $this->filesystem using a relative path.
That may be the case, but relative to what?
Initially I used $path as being the full absolute path. Then I tried a few variants of relative path, but nothing worked.
I know I could just use unlink, but I want to understand this.
This how the config file looks like:
oneup_flysystem:
adapters:
category_image:
local:
directory: "%kernel.project_dir%/public/images/category"
filesystems:
category_image_filesystem:
adapter: category_image
mount: category_image_filesystem
EDIT: Solution as proposed by Bossman
on config:
category_image:
local:
directory: "%kernel.project_dir%/public/images/category"
permissions:
file:
public: 0o644
private: 0o600
dir:
public: 0o755
private: 0o700
on controller:
$filename = $oldImage->getFilename();
if ($filename && $this->filesystem->has($filename)) {
$this->filesystem->delete($filename);
}

The original Flysystem has visibility directives within the config file for file and directory visibility, by default they are private. Make these public.
As shown in step 3:
# app/config/config.yml
oneup_flysystem:
adapters:
my_adapter:
local:
location: "%kernel.root_dir%/cache"
filesystems:
my_filesystem:
adapter: my_adapter
# optional - defines the default visibility of files: `public` or `private` (default)
visibility: private
# optional - defines the default visibility of directories: `public` or `private` (default)
directory_visibility: private
For more control the file and directory visibility properties can be set like this, like chmod:
# app/config/config.yml
oneup_flysystem:
adapters:
my_adapter:
local:
location: "%kernel.root_dir%/../uploads"
lazy: ~ # boolean (default "false")
writeFlags: ~
linkHandling: ~
permissions:
file:
public: 0o644
private: 0o600
dir:
public: 0o755
private: 0o700
