   hi friends...please help on above request..

   Hi @mubarak0443 - which version of the Chroma database (and Client library) do you use?

   Because it depends on a) version of the database (potential mismatch between client version and supported Chroma DB version), b) format of the data - whether the data inside Chroma is indeed structured in the expected format.

   Did you insert the mentioned data through this library, or using some other kind of SDK?

   Same issue here... I inserted the data using this same SDK, so the data formats should be compatible. The chromadb version is 1.5.8. The ChromaDB.Client version is 1.0.0.

   Chroma 1.x does not send data in the query response, and the client requires it. In ChromaDotNet.Client it is optional (#84).
