deleteMany with verbose: true Returns Corrupted/Garbled UUID Strings

[Shah91n]

Description:
When using the deleteMany method with the { verbose: true } option in the Weaviate TypeScript client (v3.8.0), the response does not contain the UUIDs of the deleted objects as human-readable strings. Instead, the id field for each object in the response contains garbled, binary-like data.

This behavior is wrong, which indicates that readable UUID strings should be returned.

Steps to Reproduce:

1. Connect to a Weaviate instance using the TypeScript client.
2. Execute a deleteMany operation with a filter and the { verbose: true } option.
3. Log the response or attempt to map the returned id values.

Code Example:

const collection = client.collections.get('YourCollection');
const res = await collection.data.deleteMany(
  collection.filter.byProperty("brandId").equal("someBrandId"),
  { verbose: true } // Expecting readable UUIDs in the response
);

console.log("Delete Result:", res);
// The `res.objects[].id` fields are garbled, not readable UUIDs.

Actual Result:
The response object contains successful deletion confirmation, but the id fields are unreadable.

{
  took: 10,
  failed: 0,
  matches: 20,
  successful: 20,
  objects: [
    { id: 's��Q��H��[�>�\x1D2�', successful: true, error: '' }, // Garbled ID
    // ... more objects with similarly corrupted IDs
  ]
}

Expected Result:
The response should contain standard, readable UUID strings in the id field for each successfully deleted object, as per the documentation.

{
  took: 10,
  failed: 0,
  matches: 20,
  successful: 20,
  objects: [
    { id: '208cf21f-f824-40f1-95cb-f923bc840ca6', successful: true, error: '' }, // Readable UUID
    // ... more objects with readable UUIDs
  ]
}

Environment:

• Weaviate TypeScript Client Version: 3.8.0
• Weaviate Server: 1.32.4

Full Example

import weaviate, { Filters } from 'weaviate-client';

async function main() {
  const client = await weaviate.connectToWeaviateCloud('<END_POINT>', {
    authCredentials: new weaviate.ApiKey('<KEY>'),
    headers: { 'X-OpenAI-Api-Key': '<KEY>' },
    timeout: { init: 30, query: 300, insert: 300 },
    skipInitChecks: true,
  });

  async function deleteByDirector(director: string, status: string) {
    const collection = client.collections.get('Momo');

    const filters = Filters.and(
      collection.filter.byProperty('director').equal(director),
      collection.filter.byProperty('status').equal(status)
    );

    try {
      const res = await collection.data.deleteMany(filters, { verbose: true });
      console.log("Delete result:", res);

      const itemsUuids = res.objects?.map(obj => obj.id) || [];
      console.log("Deleted item UUIDs:", itemsUuids);

      return res;
    } catch (error) {
      console.error('Error during delete operation:', error);
      throw error;
    }
  }

  await deleteByDirector("Baz Luhrmann", "Released");
}

main().catch(console.error);
