WeaviateQueryError: Query call with protocol GRPC search failed with message panic occurred: ValidateParam was called without any known params present

using the text search method from this example and getting WeaviateQueryError. weaviate-client version is 4.5.4 and weaviate sandbox version is 1.24.6. Although querying the local instance on Docker seems to be working fine
code:

import weaviate
import weaviate.classes as wvc

# Set these environment variables
URL = "some_url"
APIKEY = "weaviate_api_key"
  
# Connect to a WCS instance
client = weaviate.connect_to_wcs(skip_init_checks=True,
    cluster_url=URL,
    auth_credentials=weaviate.auth.AuthApiKey(APIKEY),
    headers={
        "X-Cohere-Api-Key": "cohere_api_Key"  # Replace with your inference API key
    }
    )

jeopardy = client.collections.get("JeopardyQuestion")
response = jeopardy.query.near_text(
    query="animals in movies",
    limit=2,
    return_metadata=wvc.query.MetadataQuery(distance=True)
)

for o in response.objects:
    print(o.properties)
    print(o.metadata.distance)

Traceback:

Hi @Debojit_Nath,

Just to be sure, did you update the URL, APIKEYand"cohere_api_Key"` values? You don’t need to share them here :wink:

Can you check if you have any data in your collection?

hopper = client.collections.get("hopper_collection")
agg = hopper.aggregate.over_all()
print(agg)

Can you check and if they have vectors?

hopper = client.collections.get("hopper_collection")
response = hopper.query.fetch_objects(
    include_vector=True,
    limit=1
)

print(response.objects[0].properties)
print(response.objects[0].vector["default"])
3

during execution I had the proper api keys and urls, getting the following while checking for data

AggregateReturn(properties={}, total_count=114)

and the following while checking for vectors

{'answers': 'some answer', 'question': 'some question'}
---------------------------------------------------------------------------
KeyError                                  Traceback (most recent call last)
Cell In[4], line 8
      2 response = hopper.query.fetch_objects(
      3     include_vector=True,
      4     limit=1
      5 )
      7 print(response.objects[0].properties)
----> 8 print(response.objects[0].vector["default"])

KeyError: 'default'

seems like while inserting data to collection the vectors were not created, I’ll try the creating a new collection and make sure the vectors are created

just figured out that I wasn’t using the vectorizer while creating the collection, now it’s working as expected, thanks for the help @sebawita :hugs:

Hi @Debojit_Nath,

I am glad you were able to find the issue.

I think we should add the example to check for vectors to a troubleshooting guide. :thinking:

Good luck with your project.
I can’t wait to see what you will build. :slight_smile:
