[Bug] Cannot list vectors, getting missing HTTP content-type error

Is this a new bug?

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

Describe the bug I have the following code:

package main

import (
    "context"
    "encoding/json"
    "fmt"
    "log"

    "github.com/pinecone-io/go-pinecone/pinecone"
    _ "google.golang.org/protobuf/types/known/structpb"
)

func main() {
    ctx := context.Background()

    client, err := pinecone.NewClient(pinecone.NewClientParams{
        ApiKey: "REDACTED",
    })
    if err != nil {
        log.Fatalf("Failed to create Client: %v", err)
    }
    index, err := client.Index(pinecone.NewIndexConnParams{
        Host:      "REDACTED",
        Namespace: "REDACTED",
    })
    if err != nil {
        log.Fatalf("Failed to initialize index: %v", err)
    }

    res, err := index.ListVectors(ctx, &pinecone.ListVectorsRequest{
        Prefix:          nil,
        Limit:           nil,
        PaginationToken: nil,
    })
    if err != nil {
        log.Fatalf("Failed to describe index stats: %v", err)
    }

    fmt.Println(res)
}

When running it I get the following output: 2024/10/24 14:04:37 Failed to describe index stats: rpc error: code = Unknown desc = malformed header: missing HTTP content-type

Error information n/a
