Are you using sentry.io or on-premise?

sentry.io (SaS)

@sentry/react-native SDK Version

6.5.0

How does your development environment look like?

Sentry.init()

Steps to Reproduce

The customer is trying to set performance metrics in a React Native app as described in the Sentry documentation on performance metrics. However, when using Sentry React Native v6.5.0, the snippet below fails with an error:

import * as Sentry from "@sentry/react-native";

const transaction = Sentry.getCurrentScope().getTransaction();
// Record amount of memory used
transaction.setMeasurement("memoryUsed", 123, "byte");

TypeError: Sentry.getCurrentScope().getTransaction is not a function (it is undefined)

Expected Result

I expect Sentry.getCurrentScope() to return a scope object with getTransaction(), per the documentation.

Actual Result

The customer gets an error that getTransaction() is undefined, and cannot record the measurement.
