I will said it again here: I have no bandwidth to look into this. It's been a few month my OSS time as vanish (sadly).

I'm open to accept more contributor into this project to help maintain it or to move it to new home (see #659)

Probably related to #667.

Is reverting change of the 14.3.3 could help for now? It will avoid to hurt to many people while we could take some time to investigate

bumping this as I just ran into this problem

So it's still a problem and it even got worse and this is why:

it's impossible to override react-element-to-jsx-string because storybook stared to bundle dependencies since storybook v8.4.0 which was released in Oct 31, 2024

I tried to bisect this problem using storybook 8.3 and this repo. So the OOM was introduced in #619 by @Andarist.

A bit later there was one more PR #660

I did not dig deep into how this lib works but as I can see if we revert #619 all tests still pass and OOM is gone

/* @flow */
import * as React from 'react';

function safeSortObject(value: any, seen: WeakSet<any>): any {
  // return non-object value as is
  if (value === null || typeof value !== 'object') {
    return value;
  }

  // return date, regexp and react element values as is
  if (
    value instanceof Date ||
-    value instanceof RegExp ||
-    React.isValidElement(value)
+    value instanceof RegExp
  ) {
    return value;
  }

  seen.add(value);

  // make a copy of array with each item passed through the sorting algorithm
  if (Array.isArray(value)) {
    return value.map(v => safeSortObject(v, seen));
  }

  // make a copy of object with key sorted
  return Object.keys(value)
    .sort()
    .reduce((result, key) => {
      if (key === '_owner') {
        return result;
      }
      if (key === 'current' || seen.has(value[key])) {
        // eslint-disable-next-line no-param-reassign
        result[key] = '[Circular]';
      } else {
        // eslint-disable-next-line no-param-reassign
        result[key] = safeSortObject(value[key], seen);
      }
      return result;
    }, {});
}

export default function sortObject(value: any): any {
  return safeSortObject(value, new WeakSet());
}

@Andarist I know that it was a long time ago (almost 4 years) but maybe you could see why it triggers OOM or do we really need this React.isValidElement check?

If it's alright to remove this check could we release this fix as 15.0.1 and 17.0.1?
