Implementation

VoxeraError voxeraTokenFailure(DioException e) {
  final error = VoxeraError.from(e);
  final status = e.response?.statusCode;
  final code = error.code;
  if (code == VoxeraErrorCode.userBanned ||
      // Engines before the error table sent a bare 403 for a ban.
      (code == VoxeraErrorCode.forbidden &&
          error.message.toLowerCase().contains('ban'))) {
    return VoxeraBannedException(error.message, status ?? 403, error.requestId);
  }
  if (status == 429) {
    return VoxeraRateLimitedException(
      error.message,
      error.retryAfter,
      code.httpStatus == 429 ? code : VoxeraErrorCode.rateLimited,
      error.requestId,
    );
  }
  if (_notAvailable.contains(code) || status == 403) {
    return VoxeraServiceNotAvailableException(
      error.message,
      status ?? 403,
      // A bare 403 from an older engine was the service not being enabled.
      code == VoxeraErrorCode.forbidden
          ? VoxeraErrorCode.serviceNotEnabled
          : code,
      error.requestId,
    );

    statusCode: status,
