Describe the bug

When upserting vectors, I get the following error:

rpc error: code = Unknown desc = malformed header: missing HTTP content-type

I have tried also adding a content-type header when creating the client with no results. I haven't tried other data plane (gRPC) functionality. I could only find one post on the community forums with the same error, but they're using grpcurl and it has no replies.

Environment

• OS Version: MacOS 14.5
• Go version: 1.22.3
• Go SDK version: 1.1.1

Additional context
I also encountered this error with previous versions of the SDK

Thanks fro reporting! @austin-denoble Can you please take a look?

Hi @fflores97, would you be able to provide any additional details or a code sample of how you're going about upserting vectors, and is this a consistent issue you're running into every time you try and upsert to an index?

We have seen this error before, but normally when trying to upsert to an index that is not in a Ready state. Are you able to verify that your index is ready through the DescribeIndex call?

I'm also seeing this when querying an pod based Index.

This was happening when passing a query vector with wrong dimensions. If this is the real root cause, could it be solved with some validation or an error message that points to it?
