SDK Setup

import * as Sentry from '@sentry/node'

Sentry.init({
  environment: ...,
  dsn: ...,
  tracesSampleRate: 1.0,
  includeLocalVariables: true,
  integrations: [
    new Sentry.Integrations.LocalVariables({
      captureAllExceptions: true,
    }),
  ],
  debug: true,
})

Steps to Reproduce

I'm trying to use @sentry/node's new includeLocalVariables (https://blog.sentry.io/local-variables-for-nodejs-in-sentry/).
I'm using Sentry SDK 7.73.0 with Node 18.15.0 (TypeScript, without ESM modules), which should work fine. But my caught errors do not show any local variables in the Sentry Dashboard.

Expected Result

Each caught error would the values of show local variables as such on the Sentry dashboard (picture from the blog post):

Actual Result

The errors show up fine as before, but no local variables can be seen anywhere from the dashboard:

But my caught errors do not show any local variables in the Sentry Dashboard

The LocalVariables integration only includes local variables for uncaught exceptions by default. This default was chosen since there might be significant overhead capturing local variables for all caught exceptions in exception heavy code. Local variables are captured via the node inpector API and this has to suspend the event loop to capture the context.

You can enable local variable capture for all exceptions via the captureAllExceptions option passed to the integration constructor:

import * as Sentry from '@sentry/node'

Sentry.init({
  ...
  includeLocalVariables: true,
  integrations: [new Sentry.Integrations.LocalVariables({ captureAllExceptions: true })],
})
