[Bug] emptyFloatList not properly initialized in Proto in 4.0.0 during Upsert

[yashrao99]

Is this a new bug?

Not sure if anyone has reported this, but when I was trying to upsert using the new SDK, it was failing internally with "cannot find class definition for emptyFloatList()"

I was only updating dense vector values, and had provided null sparse vectors/indices along with Metadata.

Either the protobuf is not initialized, or not imported properly

When I dropped to v3.1, I'm able to upsert without any issues

• [X ] I believe this is a new bug
• [X ] I have searched the existing Github issues and Community Forum, and I could not find an existing post for this bug

Describe the bug
Describe the functionality that was working before but is broken now.

Error information
I will try to append the full stack trace here, and my simple code. I am on a tight deadline right now, and 3.1 is working well. I will flip back to 4.0.0 and share the error I was receiving, but the culprit is the emptyFloatList

Steps to reproduce the issue locally
Install version 4.0.0

Call upsert method (signature with metadata)

upsert(ID, embeddings, (sparse indices == null), (sparse vector == null), "namespace", metadata struct)

Environment
Java17
