Cyclic redirect with CloudFront

See original GitHub issue

Hello,

The Lambda function is working well, but I have cyclic redirect when trying to configure it with CloudFront.

I created a CloudFront distribution with default settings and used S3’s static website endpoint as the origin. Also, I used the CloudFront domain name for the URL Lambda envonment variable.

Existing images are served well. But for new images I receive redirects loop between API gateway and CloudFront. What is interesting, new image generated and accessible with S3’s endpoint. Can’t get what is wrong.

Any ideas on how to fix it? Thank you.

No, browser redirects to API gateway again. The problem in CloudFront cache behavior ( https://docs.aws.amazon.com/en_us/AmazonCloudFront/latest/DeveloperGuide/http-3xx-status-codes.html)

Fixed by setting up CloudFlare distribution Cache Default TTL to 0 and added CacheControl to images created by Lambda:

...
.then(result =>
    S3.putObject({
        Body: result,
        Bucket: BUCKET,
        ContentType: contentType,
        Key: path,
        CacheControl: 'public, max-age=86400'
    }).promise()
)
...
