Problem use local filesystem as storage backend in ORA

[Amal MAHIOU]

HI everyone,

I want to upload openassessment student files to my local filesystem in ORA. but I get this error:

Traceback (most recent call last):

  File "/edx/app/edxapp/venvs/edxapp/src/ora2/openassessment/xblock/submission_mixin.py", line 245, in upload_url

    url = file_upload_api.get_upload_url(key, content_type)

  File "/edx/app/edxapp/venvs/edxapp/src/ora2/openassessment/fileupload/api.py", line 14, in get_upload_url

    return backends.get_backend().get_upload_url(key, content_type)

  File "/edx/app/edxapp/venvs/edxapp/src/ora2/openassessment/fileupload/backends/s3.py", line 29, in get_upload_url

    raise FileUploadInternalError(ex)

FileUploadInternalError: No handler was ready to authenticate. 1 handlers were checked. ['HmacAuthV1Handler'] Check your credentials 

Perhaps I do not know how to configure to use local filesystem. 

Could you help me to solve this?

Thanks.
