@tazarov These weird changes were fixed when I rebase the previous commit. Formatting tool leads to these changes. Thank you for your reminder.

@pig7788, this looks better. Thank you. Do you think we can also add maybe some sort of error if we don't find the response we expect? I think it would make for a good developer experience instead of returning an empty embeddings list.

@tazarov It is a good idea. I will add this in my code. Thanks!

Our underlying impl has changed and so this PR is not landable as is.

That being said - we'd still like to add this functionality and that is now tracked in this issue.
