'Cannot initialize SummaryIndex with both nodes and indexStruct'

[pelikhan]

I'm trying to understand why I am hitting this error when creating a SummaryIndex from a loaded index.

@pelikhan can you share some snippets of your code? then we can try to reproduce it.

here is a minimal repro https://stackblitz.com/edit/llamaindex-repo1?file=index.mjs

import {
  storageContextFromDefaults,
  serviceContextFromDefaults,
  Document,
  VectorStoreIndex,
  SummaryIndex,
} from 'llamaindex';

const persistDir = './db';
const storageContext = await storageContextFromDefaults({
  persistDir,
});
const serviceContext = serviceContextFromDefaults({});
const documents = [new Document({ text: 'lorem ipsem', id_: 1 })];
await storageContext.docStore.addDocuments(documents, true);
await VectorStoreIndex.fromDocuments(documents, {
  storageContext,
  serviceContext,
});
await SummaryIndex.fromDocuments(documents, {
  storageContext,
  serviceContext,
});

@pelikhan thanks for your report. I just fixed this issue in the latest main (see #567) - it will be released with the next release.
