Error message

error: {0}

What it means

A generic catch-all wrapper around anyhow::Error (#[from]). It carries an arbitrary internal error not covered by a dedicated variant, so the actual cause is inside the boxed message after the 'error: ' prefix.

Solutions

1. Read the full 'error: {0}' message to identify the inner cause
2. Check server logs for the error chain / backtrace
3. Upgrade or report to maintainers if it indicates a bug rather than user error
4. Avoid writing to compactor-internal paths; use supported public APIs

fn is_anyhow_error(err: &WriteBufferError) -> bool {
    matches!(err, WriteBufferError::AnyhowError(_))
}

match result {
    Err(WriteBufferError::AnyhowError(e)) => {
        // log the full chain to find the real cause
        log::error!("opaque write-buffer failure: {e:#}");
    }
    other => other?,
}

When it happens

Trigger: Any write-buffer operation returning an anyhow::Error from internal helpers — e.g. schema conversions, catalog operations, or plugin code that uses anyhow context.

Common situations: Internal code paths using anyhow bail/ensure without a dedicated Error variant; mixed error handling during refactors; unexpected internal conditions surfacing as opaque messages.
