Hi,

I’m using the TypeScript client v3.8.0 for Weaviate. According to the official documentation, when I use `deleteMany` with the `{ verbose: true }` option, the response should include the UUIDs of the deleted objects as readable strings in the `id` field of each object in `res.objects` (e.g., `"id": "208cf21f-f824-40f1-95cb-f923bc840ca6"`)[Delete objects: Optional parameters](https://docs.weaviate.io/weaviate/manage-objects/delete#optional-parameters).

However, in my case, the IDs returned are not readable UUID strings, but rather appear as binary or garbled data. Here is a sample of my code and the output:

```auto
const res = await collection.data.deleteMany(
  collection.filter.byProperty("brandId").equal(brandId),
  { verbose: true }
);

console.log("res DELETE", res);

const itemsUuids = res.objects.map(obj => obj.id);

```

And the output:

```auto
res DELETE {
  took: ...,
  failed: 0,
  matches: 20,
  successful: 20,
  objects: [
    { id: 's��Q��H��[�>�\x1D2�', successful: true, error: '' },
    ...
  ]
}

```

The items that have to be deleted are effectively deleted but I just dont get why the IDs are not readable strings.

The documentation does not mention this behavior, and I could not find any explanation for why the IDs are not returned as readable UUID strings.

- Is this a known issue with the TypeScript client v3.8.0?

- Is there a workaround or recommended way to get the readable UUIDs of the deleted objects?

Thank you!

hey @MELINA_BELEN_JAUREGU thanks for spotting this. Just confirmed this behaviour, could you open an issue on the [repo](https://github.com/weaviate/typescript-client/issues) so we can prioritise fixing it?

Hey @MELINA_BELEN_JAUREGU,

I’ve just replicated this locally and can confirm I’m seeing the same behavior.

```javascript
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);

```

Thank you, Daniel @malgamves - I have reported the bug below:

> <https://github.com/weaviate/typescript-client/issues/332>
>
> \*\*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:\*\*
> \`\`\`typescript
> 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.
> \`\`\`javascript
> {
> 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.
> \`\`\`javascript
> {
> took: 10,
> failed: 0,
