Some types problem in prefix vector index build

[kunga]

From #16813 (comment)

An attempt to build a prefix index

ALTER TABLE alice
ADD INDEX idx_vector
GLOBAL USING vector_kmeans_tree
ON (intent, embedding)
WITH (distance=cosine, vector_type="float", vector_dimension=1024, levels=1, clusters=200);
The attempt run gave other error. SchemeShard Schemeshard is restarting constantly.
