function collectStackTrace(

  structuredStackTrace: CallSite[],
): string {
  collectStackTracePrivate(error, structuredStackTrace);
  // At the same time we generate a string stack trace just in case someone
  // else reads it. Ideally, we'd call the previous prepareStackTrace to
  // ensure it's in the expected format but it's common for that to be
  // source mapped and since we do a lot of eager parsing of errors, it
  // would be slow in those environments. We could maybe just rely on those
  // environments having to disable source mapping globally to speed things up.
  // For now, we just generate a default V8 formatted stack trace without
  // source mapping as a fallback.
