s3s may not be configured with MIME defaults #361
Description
Bug tips
[2025-10-14 20:19:46.939081 +08:00] ERROR [s3s::ops] [/home/runner/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/s3s-0.12.0-rc.2/src/ops/mod.rs:254] [rustfs-worker:ThreadId(16)] error=S3Error { code: InvalidRequest, message: "invalid content type", source: FromStrError { inner: MissingSlash }, .. }
Possible causes
MinIO may have a default value when uploading in C++ without providing a MIME type, but s3s may not have one.
