a10y opened a new issue, #326: URL: https://github.com/apache/arrow-rs-object-store/issues/326
**Describe the bug** I've been investigating some Vortex queries on Azure Blob Store Gen2. I've created a simple storage account, populated some files, and was just trying to list the bucket on 0.12 Cargo.toml: ```toml [package] name = "rustazuretest" version = "0.1.0" edition = "2024" [dependencies] tokio = { version = "1", features = ["full"] } object_store = { version = "=0.12", features = ["azure"] } futures = "0.3" ``` main.rs ```rust use futures::StreamExt; use object_store::azure::MicrosoftAzureBuilder; use object_store::ObjectStore; #[tokio::main] async fn main() { let account = "vortexicebergsummit25"; let access_key = "REDACTED"; let container_name = "tpch"; let azure = MicrosoftAzureBuilder::new() .with_account(account) .with_access_key(access_key) .with_container_name(container_name) .build() .expect("azure object store"); let mut objects = azure.list(None); while let Some(next) = objects.next().await { println!("Object: {:?}", next.unwrap()); } } ``` On 0.12 this results in an error: ``` called `Result::unwrap()` on an `Err` value: Generic { store: "MicrosoftAzure", source: ListRequest { source: RetryError { method: GET, uri: Some(https://vortexicebergsummit25.blob.core.windows.net/tpch?&restype=container&comp=list), retries: 0, max_retries: 10, elapsed: 61.271375ms, retry_timeout: 180s, inner: Status { status: 403, body: Some("\u{feff}<?xml version=\"1.0\" encoding=\"utf-8\"?><Error><Code>AuthenticationFailed</Code><Message>Server failed to authenticate the request.
