Can't search sparse vectors with Batch search: version= 1.7.1

[Saurabh-Dadhich]

when I search with sparse separately then I am getting desired output:
output = await client.search(
collection_name=collection_name,
query_vector=models.NamedSparseVector(
name="text",
vector=models.SparseVector(
indices=query_indices,
values=query_values,
),),
query_filter=filter,
limit=1,
with_payload=True
)
->
[ScoredPoint(id=7359, version=0, score=16.72979736328125, payload={'model_type': 'test_10k_0'}, vector=None, shard_key=None)]

but with Batch Search it is failing with error:

1968 cls, model: rest.SearchRequest, collection_name: str
1969 ) -> grpc.SearchPoints:

@Saurabh-Dadhich
I have same issue and when I removed prefer_grpc=True from Qdrant connection, the issue is resolved.
So, please check if it can resolve your issue too.

[fielding]

Same issue, so the current solution is to not use grpc ? =/

[joein]

could you try qdrant-client==1.7.3 please?
