@baynezy thanks for contacting us.

Check that the files are being downloaded correctly in the network tab (you are not getting 404) and check that you have correctly configured your caching directives.

@javiercn thanks for your input. They were all returning 200 properly it just was failing with the aforementioned error.

Without making any changes it's resolved itself. So I'm pretty sure it's due to CloudFront caching. So I'll close this issue. Sorry to bother you, and thanks again.
