# TypeScript SDK - Troubleshooting and FAQ

If your issue is not covered here, please write to [support](https://smart-forms.saasjet.com/external?token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJjbGllbnRLZXkiOiJlZmZmN2JhYy0xMzZlLTNkOTUtOGIxYi1hMWQ3NWNkZWM3NGYiLCJpYXQiOjE3NTY4NDU1MTk1NzN9._OjNB4ESzMwKHLbUJPaQOjVQQqB7aCoKiCaFxhBrFoo).

# **No public key provided error appears or no traces in UI**

run the following command:

```bash theme={null}
npm update
```

# Missing traces in serverless environments

Please see the documentation on [serverless environments](/developer/sdks/js-ts/advanced-configuration)

# Missing traces with *@vercel/otel*

If you are using Next.js, please use a manual OpenTelemetry setup via the `NodeTracerProvider` than via `registerOTel` from `@vercel/otel`. This is because [the @vercel/otel package does not yet support the OpenTelemetry JS SDK v2](https://github.com/vercel/otel/issues/154) on which the `@abvdev/tracing` and `@abvdev/otel` packages are based.

If you are still missing traces, please see the documentation on [serverless environments](/developer/sdks/js-ts/advanced-configuration)
