500 error on provisioning_csv endpoint when enrollment_term_id is a number

[michaelPotter]

Summary:

For the last two days we've been getting a 500 error in the call to:

/api/v1/accounts/${account}/reports/provisioning_csv
{"parameters": {"xlist": true, "enrollment_term_id": 4550}}

Steps to reproduce:

1. Call the reports provisioning_csv api with enrollment_term_id set to a number. Note: from testing in curl, it works if enrollment_term_id is a string, e.g. "4550".

Expected behavior:

A successful response.

Actual behavior:

500 Exception code

Additional notes:

Based on the git tags, looks like there was a release on 2024-10-09 which aligns with when we started getting the error.

It also looks like there was one commit 4c5545e to app/controllers/account_report_controller.rb since the 2024-09-25 release that updated the validation on the enrollment_term_id field. I don't know ruby, but I bet this bit enrollment_term_id.split(",") is trying to call a string method on a number and crashing.
