@timothycarambat commented on GitHub (Jun 20, 2024):

LanceDBError: LanceError(IO): Query vector must have non-zero length,

This means that the embedder failed to vectorize the query and the response came back empty (0)
or
You changed the embedder at some point after documents or workspaces already had been embedded or used and now the next embedder dimensions do not match what was previously used.

What are you using as your embedder and did you even change it. Second, do you get this error on a new empty workspace?
