No bucket_id found

Error message

No bucket_id found

What it means

split_namespace found an '_' separator but the bucket_id segment it extracted is the empty string. This happens with inputs like "org_" where the underscore is present but nothing follows it. The library rejects empty identifiers because they cannot map to a valid bucket.

Solutions

  1. Supply a non-empty bucket_id after the underscore in the namespace string
  2. Validate before calling: check the substring after '_' is not empty
  3. Fix template/config interpolation so the bucket placeholder is always populated

Example fix

// before
let (org, bucket) = split_namespace("myorg_")?; // empty bucket_id
// after
let (org, bucket) = split_namespace("myorg_mybucket")?;
Defensive patterns

Strategy: validation

Validate before calling

fn has_nonempty_bucket(ns: &str) -> bool {
    ns.split_once('_').map_or(false, |(_, b)| !b.is_empty())
}

Type guard

fn split_checked(ns: &str) -> Option<(&str, &str)> {
    ns.split_once('_').filter(|(_, b)| !b.is_empty())
}

Try / catch

match split_namespace(ns) {
    Ok((org, bucket)) => /* ... */,
    Err(e) if e.to_string().contains("bucket_id") => eprintln!("bucket segment empty in '{}'", ns),
    Err(e) => eprintln!("{}", e),
}

Prevention

When it happens

Trigger: Calling split_namespace("myorg_") or any string whose characters after the single '_' are empty; also hit by test callers split_bad_empty_bucket_id and split_bad_only_underscore.

Common situations: Config or templating that interpolated an empty bucket variable into 'org_{bucket}'; trailing-underscore typos; stripping the bucket name during string manipulation while keeping the separator.
