I feel we can rewrite the function in a simpler way like below

const handleAuthError = (
  errorCode,
  authKey,
  authorizationFlow,
  sourceMessage,
  destResponse,
  status,
) => {
  if (errorCode === 'INVALID_SESSION_ID') {
    let authErrCategory = '';
    if (authorizationFlow === OAUTH) {
      authErrCategory = getAuthErrCategoryFromStCode(status);
    } else {
      ACCESS_TOKEN_CACHE.del(authKey);
    }
    throw new RetryableError(
      `${DESTINATION} Request Failed - due to "INVALID_SESSION_ID", (${authErrCategory}) ${sourceMessage}`,
      500,
      destResponse,
      authErrCategory,
    );
  }

  throw new AbortedError(
    `${DESTINATION} Request Failed: "${status}" due to "${getErrorMessage(destResponse.response)}", (Aborted) ${sourceMessage}`,
    400,
    destResponse,
  );
};
