Setup:
Locally running MinIO server (via podman quadlet).
Bucket called pixi.

Error:

While attempting to upload a package to MinIO service.

Here is the rattler-build command:

rattler-build upload s3 --endpoint-url http://127.0.0.1:9000 -vvv --channel s3://pixi/meso-forge pkgs-out/*/digitalpy*.conda

Here is the error:

thread '<unnamed>' panicked at /home/conda/feedstock_root/build_artifacts/bld/rattler-build_rattler-build_1744818186/build_env/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/opendal-0.53.0/src/raw/http_util/client.rs:160:58:
input request url must be valid: InvalidIpv4Address

Authentication is done using the RATTLER_AUTH_FILE:

{
    "s3://pixi/meso-forge": {
        "S3Credentials": {
            "access_key_id": "<secret>",
            "secret_access_key": "<secret>",
            "session_token": null
        }
    }
}

I doubt that the "InvalidIpv4Address" error is complaining about 127.0.0.1.
My local MinIO service UI is working fine on http://127.0.0.1:9001 .
