Visualization Fails with Multi-Vectors When Vector Counts Differ Across Documents

[JirkaKlimes]

Description

When attempting to run visualization in the Qdrant Web UI using multi-vectors (i.e., a 2D array or multiple same-sized vectors for a single document), the visualization process fails if the number of vectors varies across multiple documents. In my use case, each document contains multiple keys, each associated with an embedding. To simplify the data structure and avoid duplication, I consolidate all embeddings into a single document using multi-vectors. However, this approach leads to a visualization error.

Error Message

Uncaught Error: various array lengths
