Reproduction Example/SDK Setup

Sentry.init({
    dsn: SENTRY_DSN,
    attachStacktrace: true,
    includeLocalVariables: true,
    release: VERSION,
    tracesSampler: ctx => {
        console.log("tracesSampler ctx", ctx.custom)
        return 0
    },
    profilesSampler: ctx => {
        console.log("profilesSampler ctx", ctx.custom)
        return 0
    },
    integrations: [
        new Sentry.Integrations.LocalVariables({
            captureAllExceptions: true,
        }),
        new Sentry.Integrations.ContextLines({
            frameContextLines: 12, // Default is 7
        }),
        new Sentry.Integrations.Http({
            tracing: true,
        }),
        // Enable node profiling
        nodeProfilingIntegration(),
    ],
})

Steps to Reproduce

1. Initialize Sentry with tracesSampler and profilesSampler callbacks.
2. Send custom context when starting transaction (startTransaction).
3. Get custom context in the profilesSampler callback.

const transaction = Sentry.getCurrentHub().startTransaction({ name: `XXX` }, { custom: 'XXX' }) as
    | Sentry.Transaction
    | undefined

Expected Result

Custom context is passed.

Actual Result

Custom context is not passed.
