Importmap CORS issue

1

I am adding ActionText / Trix into existing Rails 6 app without Webpacker.

Everything is working fine in dev through importmap-rails gem.

In production, assets are served from s3/cloudfront bucket. All of the other assets are being fetched without any issues as before.

New application.js is blocked though and console is warning:

Access to script at 'https://dildaikntvx6.cloudfront.net/cd/assets/application-110db9dec93064a75e0f73152b58569feb67a14897731137dfc92098d8388b0a.js' from origin 'https://cakesdecor.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I tried to make the respective file public in S3 and also added CORS policy:

[
    {
        "AllowedHeaders": [
            "*"
        ],
        "AllowedMethods": [
            "GET"
        ],
        "AllowedOrigins": [
            "https://cakesdecor.com"
        ],
        "ExposeHeaders": []
    }
]
