@EvanMarth Can you take some screenshots and attach here. Also, I would say this error seems client side issue, so HAR extract may be required.

Here's how to extract the HAR file in Chrome while you are reproducing this issue:
1. Right-click in the browser window or tab and select Inspect.
2. Click the Network tab in the panel that appears.
3. Navigate to the URL you want to traffic.
4. Click the download button. (Export HAR appears when you hold the pointer over it.)
5. Name the file.
6. Click Save.
