Lambda does not exit on errors, keeps running until timeout

Describe the bug

I haven't tested it super thoroughly, but I saw Lambda runs till max timeout even thought it couldn't process anything. One example was sending gz files which I realized not supported

Steps to reproduce (if applicable)
Steps to reproduce the behavior:

1. deploy indexer lambda
2. send compressed file, test.json.gz

Expected behavior

It should exit immediately and not run until timeout

Configuration:

export class RustFunction extends Function {
  constructor(scope: Construct, id: string, props?: Partial<FunctionProps>) {
    const lambdaAssetPath = path.join(
      __dirname,
      "../../quickwit/quickwit",
      "quickwit-lambda/deploy",
      id
    );
    console.log("lambdaAssetPath", lambdaAssetPath);
    super(scope, id+'_f', {
      ...props,
      code: Code.fromAsset(lambdaAssetPath),
      handler: id, // use id to specify either "indexer" or "searcher"
      runtime: Runtime.PROVIDED_AL2,
      architecture: Architecture.ARM_64,
      logRetention: RetentionDays.ONE_DAY,
      tracing: Tracing.DISABLED,
    });
  }
}

Binaries compiled with this command (I didn't use cross it was too slow on Mac)

LIBZ_SYS_STATIC=1 TARGET_CC=aarch64-linux-musl-gcc RUSTFLAGS="-C linker=aarch64-linux-musl-gcc -C link-arg=-static -C opt-level=z -C lto" cargo build --release --target aarch64-unknown-linux-musl

Start by inspecting the quickwit-lambda/deploy entry points used for the indexer and searcher handlers, then reproduce the reported behavior by sending test.json.gz to the deployed indexer Lambda. Done means an unsupported compressed file causes the Lambda to exit immediately instead of running until its maximum timeout.
