500 error when an Opportunity is not found

[mdragon]

Summary

Instead of getting a 404 error/page when an opportunity is accessed that no longer exists we're instead throwing 500 errors. This problem seems to have been introduced with Release 2025.02.19-1. This is a front end issue, the API is correctly responding with a 404. This caused the Cloudwatch Alert for FE 500 errors to fire off this morning, likely due to Google or other crawling based on the errors/minute counts. Likely will need to re-crawl affected pages via Google console once the issue has been resolved.
