Return format collection.batch.failed_objects

Support

Hi,
I can not find any information of the exact return format of collection.batch.failed_objects. I need to make sure that my application handles this error correctly and retries failed objects, but without knowing the exact format of the returned objects I can not do that. Can anyone help me out?

Thank you in advance!

hi @Oasis !!

Welcome to our community :hugs:

You can provoke that error, like so:

collection = client.collections.delete("Test")
client.collections.create("Test")

with client.batch.dynamic() as batch:
    batch.add_object(
        collection="Test",
        properties={"text": "object1"},
        vector=[1,2]
    )
    batch.add_object(
        collection="Test",
        properties={"text": "object2"}, 
        vector=[1,2,3]
    )

if client.batch.failed_objects:
    print(f"Found {len(client.batch.failed_objects)} failed objects" )
    print(client.batch.failed_objects)

this will be the output:

Found 1 failed objects
[ErrorObject(message=‘inconsistent vector lengths: 3 != 2’, object_=BatchObject(collection=‘Test’, properties={‘text’: ‘object1’}, references=None, uuid=‘378e10c3-e63a-44ab-bcaf-e41792e69b3c’, vector=[1, 2], tenant=None, index=0, retry_count=0), original_uuid=‘378e10c3-e63a-44ab-bcaf-e41792e69b3c’)]

Let me know if that helps!

Hey, all of our output is typed and will be stable.

You can import the definitions of the returned type here:

from weaviate.outputs.batch import ErrorObject

collection.batch.failed_objects returns List[ErrorObject]
