/v3/ClassSchedules/{termCode}/{courseId} returns "500 Server Error"

[jfavery]

Querying this endpoint returns a "500 Server Error".
{{baseURL}}/v3/ClassSchedules/1259/016287

This is a valid courseID for term 1259 (it's my course). I can find schedule data if I instead use the subject + course code.

e.g., this works
{{baseURL}}/v3/ClassSchedules/1259/CS/346
{
"courseId": "016287",
"courseOfferNumber": 1,
"sessionCode": "1",
"classSection": 101,
"termCode": "1259",
"classNumber": 6947,
"courseComponent": "LAB",

Hi,

This should be fixed now. There was some clean up around left over code from showing instructor data that triggered the issue.

If you can confirm, that would be great.

Also if you have a moment, can you describe briefly the workflow/purpose of your use of this API/data? The context is there's debate about the life cycle of this API, and understanding staff/internal use cases like this is helpful.

Thanks for the quick response! It works fine now, both in my postman tests and my app.

I'm CS faculty, and I'm also an academic advisor. I actually use this API in both capacities.

1. Advising applications

I've written a few small applications to help us with advising. e.g.,

$ courses CS 346 --sections
CS 346: Application Development
Fall 2025 (1259)

Introduction to full-stack application design and development. Students will work in project teams to design and build complete, working applications and services using standard tools. Topics include best-practices in design, development, testing, and deployment.

Prerequisites: CS 246/246E or CS 247. Honours Computer Science, Honours Data Science (BCS), BCFM, BSE students only
Corequisites: None
Antirequisites: None

LAB 101 62/72
LAB 102 46/72
LEC 001 62/72
LEC 002 46/72

2. Teaching

I also teach a third year application development course, CS 346.

I use this API for demos in-class since the data is meaningful to students. They also build full-stack applications in Kotlin, and a few teams each term will build apps against the API. Not surprisingly, students like building applications that support their studies/academics.

I'm happy to talk more about this if it's helpful.

Best,
Jeff
