When using the node library, I get this error periodically (usually shortly after the server restarts) when trying to query a namespaced index using

```auto
await index.namespace(pineconeNameSpace).query({
                    topK: k,
                    vector: queryEmbedding,
                    includeMetadata: true,
            });

```

Error below

```auto
499 | var _a;
500 | return __generator(this, function (_b) {
501 | switch (_b.label) {
502 | case 0:
503 | _a = this.transformer;
504 | return [4 /*yield*/, this.raw.json()];
                                                   ^

```

Trace

Hi @waelsahhar – are you using bun? we’ve encountered something similar in bun so that would help us debug.

Hi,

We are using Bun (v1.1.22) and just encountered this issue. It’s not all the time, but frequent enough to be problematic.
