Issue details

With a cache policy like this:

        const cachePolicy = new aws.cloudfront.CachePolicy('api-cache-policy', {
            comment: "api requests with CORS caching enabled",
            minTtl: 0,
            defaultTtl: 0,
            maxTtl: 86400,
            parametersInCacheKeyAndForwardedToOrigin: {
                headersConfig: {headerBehavior: "whitelist", headers: {items: headers}},
                cookiesConfig: {cookieBehavior: "none"},
                queryStringsConfig: {queryStringBehavior: "all"}
            }
        })

The creation of the policy works as expected, however subsequent updates fail because the policy is sent without the defualtTtl:

This was fixed recently in hashicorp/terraform-provider-aws#21793 and will be picked up on the next release of the provider.

closing this out as we have since updated to a version that picks this up
