Summary

Testing Plan

• Was this tested locally? If not, explain why. - No tests break because nothing is using the xhr uploader and testing a status greater than 300. However, this test in Alias Requests fails before this fix, and passes afterwards, showing that this change works.
• {explain how this has been tested, and what, if any, additional testing should be done}
