GET `/v3/ClassSchedules/{termCode}/{courseId}` returns 404

[AD1938]

Hey! I am trying to fix https://uwflow.com/ 's importer and noticed the endpoint /v3/ClassSchedules/{termCode}/{courseId} is returning 404 errors:

{
  "type": "https://tools.ietf.org/html/rfc9110#section-15.5.5",
  "title": "Not Found",
  "status": 404,
  "traceId": "00-6b1a3b332e6ed23321acb4dabbbda5a8-192df039434c6cf3-00"
}

I am trying with termCode = 1265 and a lot of course IDs returned from GET /v3/ClassSchedules/1265, all of them seemed to give above response body.

Wondering if this would get fixed, thank you!

Hi, thank you for reporting. I'll take a look; there were some data load failures due to network issues last night, but in this case it looks like there may be an unrelated issue causing this.

I'll try to have an update by Friday.

I've made an update, which for full disclosure did not get a lot of testing. There was a bug in caching which would cause unintended 404 responses even if we did have data for the class. Can you give it a try again and see if you run into issues? I've tried a few spot requests for schedules for reference.

While we're working through this; can you confirm which API key you use by emailing to sbobkin@uwaterloo.ca please. We disabled one key that looked like it was associated to UW flow a while back.

Thank you! I tried a few, looks like some class schedules are working but some are still experiencing 404s. For example last few courses in the array returned by https://openapi.data.uwaterloo.ca/v3/Courses/1265 are problematic

Emailed as well.

Hi,

Could you provide the course IDs that you think are an issue?

[AD1938]

Hello, looks like a lot of data is back, thank you.
Just an example, course ID 016954 is returned by https://openapi.data.uwaterloo.ca/v3/Courses/1265 but https://openapi.data.uwaterloo.ca/v3/ClassSchedules/1265/016954 returns 404.

Oh, okay, I understand now.

I answered this here and the pattern that will a) fix this, and b) lower the amount of requests you need to do #241 (comment)

Let me know if I can clarify more.
