3. Choose > Week 7 > Week 7 Sequence 1 > [3rd] Survey (you do not need to choose "Classes and Instructors" but you can. The result is the same)

Actual Result

Error: There was an error generating your report.

Expected Result

A downloadable CSV is created

Sentry error with stack trace

We're not sure how usable the captured date was, but if we could catch the assert error and do something else that allows the report to continue, we might be able to get more data into the report.

FYI: The issue can be reproduced by creating some inconsistency in the question problem. You can follow the below steps to reproduce the issue: 1) Create a checkboxes problem 2) Add N options under that problem (where N is a number) 3) Go to LMS, select and submit Nth option 4) Go back to the studio and update the question by removing the Nth option (now the total options will be N-1) 5) Try generating a response report for that problem, it will give Error: There was an error generating your report. error.

@pdpinch can we close this?

I’d like to see it deployed to lms.mitx.mit.edu first and confirm that it fixes the problem with the course.

[HamzaIbnFarooq]

Oh, sorry, I thought it's deployed. Please keep me updated as I have to update its related upstream PR (https://github.com/edx/edx-platform/pull/27858)

[HamzaIbnFarooq]

FYI: Its upstream PR (https://github.com/edx/edx-platform/pull/27858) has been merged.
