While Batch Insertion of data, shows Batch Connection Error due to network error and retries some time . If I try to catch that Exception ,after catched It shows retries. I need to handle Exception after all retries are exhausted how to achieve this.

def insert(class\_,obj\_count):  
vector\_val = [[random.random() for \_ in range(128)] for \_ in range(obj\_count)]  
start = time.time()

```
with client.batch as batch: # automatically calls flush()
    for id_, vec in enumerate(vector_val):
        data_obj = {
            "unique_id": id_
            }
        batch.add_data_object(
                data_obj, 
                class_, 
            vector=vec 
            # generate_uuid('Sample',doc), # if not provided, it generates automatically
            )

    print(time.time() - start)
    print(f"Finished importing data for {class_} Object Count :{obj_count}")

```

Hi Dharanish!

Check this for error handling in batch imports:

> **[REST - /v1/batch | Weaviate - Vector Database](https://weaviate.io/developers/weaviate/api/rest/batch#error-handling)**
>
> Batch create objects

Tip: If you want to force an error, you can insert an object with 2 dimensions, then a second one with 3 dimensions.

Check this issue here for more on error handling:

> (Note: I'm encountering this issue using the p…ython client, so I wasn't sure if this repository or the python client one was preferred - however as it is documentation related I've put it here. Let me know if I should move it.)

> I want to ensure that I can detect if a batch delete has been successful - so checking the documentation...
> 
> Under the \*\*Error handling\*\* section on the \*\*References: API \> RESTful API \> REST - /v1/batch\*\* page, the code in the \`check\_batch\_result\` has the following:
> 
> \`\`\`
> if results is not None:
> for result in results:
> if 'result' in result and 'errors' in result\['result'\]:
> if 'error' in result\['result'\]\['errors'\]:
> print(result\['result'\]\['errors'\]\['error'\])
> \`\`\`
> 
> This code was causing an exception on the third line where it was looking for 'errors' in result\['result'\].
> 
> I believe there's an \`objects\` element under the \`results\` element and that each of those object elements has an \`error\` element.
> 
> As I'm not sure how to cause an error in order to test for it I've updated the code, which runs, but I haven't been able to cause an error to test it.
