Tutor Richie error on sync

Tutor Plugins
1

I’m just install tutor with command tutor local quickstart and add Richie plugin. New courses don’t showed in Richie, than I’m trying to reinitialize and get error.
ERROR 8 [richie.sync] [user None] [ip None] sync.py:67 - Could not synchronize course course-v1:ACI+Test_C+2021_12 with Richie. Response: {"resource_link":["Unknown course: TEST_C."]}

+1, I’m getting the same issue on my end:

cms_1 | 2021-12-15 13:01:38,256 ERROR 8 [richie.sync] [user 6] [ip 72.218.28.34] sync.py:67 - Could not synchronize course course-v1:Edunomic+CS101+2014_T1 with Richie. Response: {"resource_link":["Unknown course: CS101."]}

I’m troubleshooting and will report back if I find anything but it’s a bit of a labyrinth finding issues in Richie!

I tried running tutor local run richie ./sandbox/manage.py richie_init (only because it was under the header of ‘courses’ and these entries in the logs caught my eye:

Not sure if this is relevant but I’m assuming so for now.

Further updates. Using the example python code at Synchronizing course runs between Richie and OpenEdX · Richie I tried to run a manual sync using the secret from tutor.py:

Python 3.7.12 (default, Oct 22 2021, 17:50:30)
[Clang 13.0.0 (clang-1300.0.29.3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import hashlib
>>> import hmac
>>> import json
>>> import requests
>>> data = {
    "resource_link": "https://edunomic.academy/courses/course-v1:Edunomic+BC101+2021_Q4/course",
    "languages": ["en"]
}
>>> signature = hmac.new(
... "SECRET_KEY_GOES_HERE".encode("utf-8"),
... msg=json.dumps(data).encode("utf-8"),
... digestmod=hashlib.sha256,
... ).hexdigest()
>>> response = requests.post(
... "https://courses.edunomic.academy/api/v1.0/course-runs-sync/",
... json=data,
... headers={"Authorization": "SIG-HMAC-SHA256 {:s}".format(signature)},
... )

The result was the same as what we’re seeing in the logs:

>>> print(response)
<Response [400]>
>>> print(response.content)
b'{"resource_link":["Unknown course: BC101."]}'

Sadly not a solution but at least it’s manually testable and reproducible. I’m assuming the Course needs to be there before Course Runs can be synced, however:

  1. No course sync took place
  2. There is no “Create Course” option in the CMS wizard
  3. The docs make no mention of this

SOLVED UPDATE:

See the issue submitted to the richie project: Error synchronizing Richie <-> Tutor with the tutor-richie plugin · Issue #1544 · openfun/richie · GitHub

The solution is indeed that the course needs to exist on the Richie side before you can sync. To create a course, you must:

  1. Create an organization
  2. Go to the organization page
  3. Click ‘Create’ in the top right bar (CMS bar)
  4. Select Create Course

After that, new course runs will sync.
