500 errors for Resizer v1 URLs in my logs after migration to Resizer v2

500 errors for Resizer v1 URLs
Cause
If you're only seeing this in logs, and they are v1 URLs, these errors are tied directly to our resizer v1 to v2 redirector solution.
Solution
Readers will not see this error, it's purely internal to the redirector logic where we are triggering a failover to get redirects to follow. You should not be alarmed by this. However, if you suspect this is related to an issue, reach out to ACS to investigate.
