AWS S3 Multipart Uploads scenarios with 403 Forbidden scenarios on Specific Regions
I need some guidance on I'm dealing with I've looked through the documentation and I'm still confused about I'm currently implementing a large file upload feature using AWS S3's multipart upload capability with the AWS SDK for JavaScript (v3)....... Everything works perfectly in the `us-east-1` region. However, when I try to perform uploads in the `eu-west-1` region, I'm working with a `403 Forbidden` behavior. I've ensured that the IAM role associated with my Lambda function has the correct permissions: ```json { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "s3:PutObject", "s3:PutObjectAcl", "s3:CreateMultipartUpload", "s3:UploadPart", "s3:CompleteMultipartUpload" ], "Resource": "arn:aws:s3:::my-bucket/*" } ] } ``` I've also verified that the bucket is correctly configured to allow public access, but I've set the `Block Public Access` settings to restrict access. The bucket policy is as follows: ```json { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": "*", "Action": "s3:*", "Resource": "arn:aws:s3:::my-bucket/*" } ] } ``` When I make the request, I log the behavior response, which gives me this message: `Access Denied` with a status code of `403`. The upload process works as expected in `us-east-1`, so I suspect there might be some regional configuration or cross-region permissions scenario that I'm missing. I've tried both the AWS Console and the SDK for uploads, and they both yield the same result. Is there something specific to the `eu-west-1` region that could be causing this scenario, or best practices I might be overlooking? My development environment is Ubuntu. What's the best practice here? Thanks in advance! My development environment is Linux. Any feedback is welcome! I'm using Javascript 3.11 in this project. Has anyone dealt with something similar?
