Pagefind is unavailable.

Error message

Pagefind is unavailable.

What it means

This is a panic raised by `.expect("all required builder params specified")` on the aws-sdk-sqs `DeleteMessageBatchRequestEntry` builder. The SDK builder's `build()` returns a Result and fails when a mandatory field (`id` or `receipt_handle`) was never set. In this call site both fields are set unconditionally from a successfully processed message, so the expect documents the invariant that the build cannot fail; if it fires, the surrounding code's invariant is broken (e.g. a None receipt_handle was force-unwrapped or an SDK version changed builder semantics).

Solutions

1. Verify the aws-sdk-sqs version against vector's Cargo.lock/Cargo.toml and restore matching field setters if the builder API changed.
2. Check that `receipt_handle` is a non-Option String built from `message.receipt_handle` before the loop and is not moved/consumed in earlier iterations.
3. If a runtime failure is possible, replace `.expect()` with proper error handling that emits `SqsMessageDeleteError` and skips the entry instead of panicking the source task.

Example fix

// before
DeleteMessageBatchRequestEntry::builder()
    .id(message_id.clone())
    .receipt_handle(receipt_handle)
    .build()
    .expect("all required builder params specified")
// after
DeleteMessageBatchRequestEntry::builder()
    .id(message_id.clone())
    .receipt_handle(receipt_handle)
    .build()
    .unwrap_or_else(|e| panic!("SQS delete entry build failed: {e}"))

fn valid_delete_entry(id: &str, receipt_handle: &str) -> bool {
    !id.is_empty() && !receipt_handle.is_empty()
}

fn as_receipt(m: &Message) -> Option<&str> { m.receipt_handle.as_deref().filter(|r| !r.is_empty()) }

// Rust: replace .expect with match on build Result
match DeleteMessageBatchRequestEntry::builder().id(id).receipt_handle(rh).build() {
    Ok(entry) => entries.push(entry),
    Err(e) => { emit!(SqsMessageDeleteError { error: &e.into() }); }
}

When it happens

Trigger: Calling `DeleteMessageBatchRequestEntry::builder().id(..).receipt_handle(..).build()` without setting `id` or `receipt_handle`. In vector's `run_once` (src/sources/aws_s3/sqs.rs:486) this only triggers if `receipt_handle` extraction produced None that was unwrapped earlier, or an aws-sdk upgrade made additional fields required.

Common situations: Upgrading the `aws-sdk-sqs` crate to a version where the builder gained a new required field; refactoring the delete loop and accidentally dropping a `.receipt_handle()` call; a receipt_handle Option being consumed/moved after the first message in a batch so later iterations build with None.
