On a loosely related note, I don't suppose there is any way to attach a listener to Typesense.client so that I can log the raw queries/data that are getting passed to the typesense API, is there? I'm just thinking that it would be a useful feature to help me troubleshoot this kind of thing in future.

AFAIK, you could use an axios global interceptor to catch any outgoing request to Typesense and use that. The debug logger also logs out the requests (albeit without the body contents, just responses and endpoints) if you want a quicker look. We intend to update the library to let you pass an axios instance on Client instantiation to give you more control for Axios
