Thank you!

The additional steps may be:

1. Trigger the TF apply for prod (actually not sure if Erik did this...)
2. Clear Cloudfront cache (Erik had to do this but not 100% sure if this is necessary to make it work)

Looks like Erik already added the Origin header to the cache policy in prod and can see it in the AWS console. I’ll merge and test and clear the cache if it’s not working.
