Situation: my space has articles and posts. Article A has a multiple reference field with "related posts" that includes Post B. Post B has a multiple reference field with "related articles", that includes Article A.

If I run a build at which I try to sync my items with Algolia, the following happens.

Error message:
RangeError: Maximum call stack size exceeded at Contentful._cleanMore (/Users/Sander/GitHub/gatsby/blog/node_modules/contentful-to-algolia/lib/Contentful.js:171:15)

Bug sits in _getLocalForNestedFields. If I comment out lines 134 to 151 and simply delete the circular array (like delete entry[key]) - the error is gone.

Hello!

I am able to successfully use the contentful-to-algolia integration to import Contentful data into Algolia without any entry manipulation. Now, I would like to test changing the shape of the JSON so that entries are only indexed with specified properties.

My question is related to using the manipulateSingle function. The sync method works when I specify the content type ID, index name, and callback function parameters:

Sync.sync(
  <contentTypeID>,
  <indexName>,
  <callback function>
);

The last two parameters are what I am having issues with. Do I need to specify the <entryId> parameter? I don't want to so I have been testing out values such as undefined and false but I get the error that a string is expected. What I care about is being able to run the manipulateSingle function. If I don't put anything in the <entryID> parameter and use this:

Sync.sync(
  <contentTypeID>,
  <indexName>,
  <callback function>,
  <manipulateSingle>
);

The sync works, entries are imported, and I don't get errors in the console. However, the manipulateSingle function is ignored and my entries are not indexed with their new shape.

What am I doing wrong?

Here is what I am trying to get to work:

const formatter = ({
  id,
  createdAt,
  locale,
  productName,
  slug,
  productDescription,
  tags,
  contentType
}) => ({
  id,
  locale,
  objectID: id,
  createdAt,
  productName,
  slug,
  productDescription,
  tags,
  contentType
});


Sync.sync(
  '2PqfXUJwE8qSYKuM0U6w8M',
  'blog',
  function(algolia_response) {
    const response = algolia_response;
    console.log('res', JSON.stringify(algolia_response));
    console.log('number of indexed entries:', algolia_response.length);
  },
  // undefined,
  formatter
);

Thanks so much!

👋 I'm using contentful-to-algolia on a project and I had a question about this commit. In _cleanEntry on line 97 it will access entry.sys.contentType, but the array of entries being sent to this code includes objects representing assets, which do not include the contentType key.

I'm just curious which API you're using to build this library. I ran into the above error with the Delivery API, and I know some of Contentful's APIs deliver data in different formats.

Thanks for making this library though, it's been a big help.

I have a content type with over 1000 entries, but the library currently only processes 100 entries. This feature could be implemented using the skip and limit parameters. Thoughts?

See https://discourse.algolia.com/t/sync-content-from-contentful-to-algolia-indexes/415/5

Is there any way to filter out entries based on their content?
Looks like returning null from manipulateSingle does not work.
