ecommerce basket issue

[Alden Jones]

I have ecommerce running on a Eucalyptus Fullstack installation. I followed all the installation and configurations docs I could find and I'm able to access the CAT as well as the Oscar Dashboard and add classes. I'm having trouble adding courses to the basket though, when I try to enroll in a course I get a JSON error:

JSONDecodeError at /basket/

Expecting value: line 9 column 1 (char 8)

Request Method: GET

Request URL: http://localhost:18130/basket/

Django Version: 1.8.16

Exception Type: JSONDecodeError

Exception Value:

Expecting value: line 9 column 1 (char 8)

Exception Location: /edx/app/ecommerce/venvs/ecommerce/local/lib/python2.7/site-packages/simplejson/decoder.py in raw_decode, line 404

Python Executable: /edx/app/ecommerce/venvs/ecommerce/bin/python

Python Version: 2.7.10

Python Path:

 '/edx/app/ecommerce/ecommerce/ecommerce',

 '/edx/app/ecommerce/ecommerce']

Things are, to the best of my knowledge, all set in the lms.env.json, lms.auth.json, and ecommerce.yml files... Is there another place I have to set flags? I'm able to directly access /receipt/ and /checkout/ there just seems to be an issue accessing the basket.

Thanks!

Alden,

Can you share more information—specifically, a stack trace. Based on what you have provided, it is unclear why your installation is having issues.

[Adithya Soman]

Hi Alden,

I believe you have installed master version of ecommerce, Try installing open-release/eucalytptus.1 or open-release/eucalytptus.2 

replace ECOMMERCE_VERSION and  ECOMMERCE_WORKER_VERSION:  variable with the version which you want to install.

Thanks

Thanks for attempting to help... I pulled lms and ecommerce logs from today 

This is the latest entry in the lms log:

ValueError: Cannot assign None: "AccessToken.user" does not allow null values.

Make sure you have a user associated with your OAuth 2 client. We usually use a service user (e.g. ecommerce_user) with staff permissions for this purpose. When you make server-to-server calls using the client credentials authentication method, this is the user for whom an access token will be issued.

Thanks Clinton, that worked like a charm!

[Trinh Nguyen]

Thanks Clinton, this works:

"Make sure you have a user associated with your OAuth 2 client..."
