Default file storage s3 error media path

I am getting the below error while running the application.

    raise ImproperlyConfigured(
django.core.exceptions.ImproperlyConfigured: S3Boto3Storage.location cannot begin with a leading slash. Found '/openedx/media/'. Use 'openedx/media/' instead

I tried with a patch using tutor plugins to remove the leading slash but the error still exists.

name: custom-settings
version: 0.1.0
  openedx-common-settings: |
     MEDIA_ROOT = "openedx/media/"
     DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'

Tutor version 12.01(lilac)

Hi ashraf,

Set these under openedx-common-settings:

    VIDEO_IMAGE_SETTINGS["STORAGE_KWARGS"]["location"] = "openedx/media/"
    VIDEO_TRANSCRIPTS_SETTINGS["STORAGE_KWARGS"]["location"] = "openedx/media/"

This is caused by tutor using directly MEDIA_ROOT in the video structs when creating settings files. The original playbook makes a finer work by checking if the default storage is s3 and removing the leading slash.

Are you using the tutor-minio plugin to host assets on S3? This plugin takes care of correctly defining these setting values (and they are highly non-trivial):
