What component(s) are affected?

• [ ] Opik Python SDK
• [x] Opik Typescript SDK

• [ ] Opik Server
• [ ] Documentation

Opik version

• Opik version: 1.8.52

Describe the problem

If we use OpikExporter with registerOTel, it throws TypeError: Cannot read properties of undefined (reading 'name') error.

It seems @vercel/otel doesn't support otel 2

https://github.com/vercel/otel/issues/154

So instrumentationScope can't be used but it was replaced on https://github.com/comet-ml/opik/pull/2174

Reproduction steps and code snippets

import { OpikExporter } from "opik/vercel";
import { registerOTel } from "@vercel/otel";

registerOTel({
  traceExporter: new OpikExporter(),
});

Hi @mtsmfm, could you share the version of your packages and Node? I cannot reproduce locally with those versions:

  "dependencies": {
    "@ai-sdk/openai": "^2.0.32",
    "@vercel/otel": "^1.13.0",
    "ai": "^5.0.49",
    "opik": "^1.8.52"
  },
