Error message

<transparent: MultiTenantExtractError>

What it means

This is a transparent wrapper in iox_http's WriteParseError for MultiTenantExtractError. It occurs when parsing a multi-tenant HTTP write request fails; the inner error (itself possibly wrapping OrgBucketMappingError or V2WriteParseError) is displayed unchanged. The codebase converts &WriteParseError to a hyper::StatusCode, so the content is often reduced to an HTTP code in responses.

Solutions

1. Read the inner MultiTenantExtractError (and its nested cause) for the exact failure.
2. Validate org, bucket, precision, and body encoding against the v2 write API before sending.
3. Check the mapped HTTP status code returned to identify the parse stage that failed.
4. Upgrade/align client SDK and server API versions.

Example fix

// before
let resp = client.post("/write").body(raw).send().await?; // may 4xx with parse error
// after
let params = WriteParamsV2::new(ns, Precision::Nanosecond).try_into()?; // validate first
if let Err(e) = &params {
    eprintln!("write params invalid: {e}");
    return Ok(status_response(e));
}

// Rust: pre-flight multi-tenant write params
fn multi_tenant_write_ok(org: &str, bucket: &str, body: &str) -> bool {
    !org.is_empty() && !bucket.is_empty() && !body.trim().is_empty()
        && !org.contains('/') && !bucket.contains('/')
}

fn is_multi_tenant_err(e: &WriteParseError) -> bool {
    matches!(e, WriteParseError::MultiTenantError(_))
}

When it happens

Trigger: POSTing to the multi-tenant write endpoint where request extraction fails: unparseable WriteParamsV2 or unmappable org/bucket namespace.

Common situations: v2 write protocol misuse; missing or invalid org/bucket; version drift between client SDKs and the IOx HTTP API.

Understand the failure class

Background: Schema validation failed / invalid input schema: payload rejected because its shape doesn't match the expected schema — this error's family across 28 libraries.
