### Description

I’m trying to batch import data into a collection like so:

```auto
with filings_collection.batch.dynamic() as batch:
    for fc in tqdm(filngs_chunked):
        batch.add_object(
            properties=fc,
        )

```

I’m having trouble catching errors. I find that there is a number\_errors attribute, however this doesn’t tell me which object exactly has failed, or what the error is

Hello @md1639,

Welcome to our community! it’s great to have you here 🤗

You can consider capture more information about errors and failed objects by implementing error handling and logging during the batch process by using **client.batch.failed\_objects & client.batch.failed\_references.**

### Error Handling →

> **[Python | Weaviate Documentation](https://docs.weaviate.io/weaviate/client-libraries/python)**
>
> Official Python client library documentation for integrating Weaviate with Python applications and services.

You will find a good example in the documentation:

> failed\_objs\_b = client.batch.failed\_objects # Get failed objects  
> failed\_refs\_b = client.batch.failed\_references # Get failed references

Additionally, Weaviate Pythin Client, the following exception handling can help raises various error conditions:

- `weaviate.exceptions.WeaviateConnectionError` for failed connections.
- `weaviate.exceptions.WeaviateQueryError` for failed queries.
- `weaviate.exceptions.WeaviateBatchError` for failed batch operations.
- `weaviate.exceptions.WeaviateClosedClientError` for operations on a closed client.

You can review [this module](https://github.com/weaviate/weaviate-python-client/blob/main/weaviate/exceptions.py) which defines the exceptions that can be raised by the client library.
