SDK Setup

Client

// This file configures the initialization of Sentry on the browser.
// The config you add here will be used whenever a page is visited.
// https://docs.sentry.io/platforms/javascript/guides/nextjs/

import * as Sentry from '@sentry/nextjs'

const SENTRY_DSN = process.env.SENTRY_DSN || process.env.NEXT_PUBLIC_SENTRY_DSN

Sentry.init({
 dsn: SENTRY_DSN',
 tracesSampleRate: process.env.NODE_ENV === 'production' ? 0.1 : 0.3,
 environment: process.env.NODE_ENV,
 // ...
 // Note: if you want to override the automatic release value, do not set a
 // `release` value here - use the environment variable `SENTRY_RELEASE`, so
 // that it will also get attached to your source maps
})

Server

// This file configures the initialization of Sentry on the server.
// The config you add here will be used whenever the server handles a request.
// https://docs.sentry.io/platforms/javascript/guides/nextjs/

import * as Sentry from '@sentry/nextjs'

const SENTRY_DSN = process.env.SENTRY_DSN || process.env.NEXT_PUBLIC_SENTRY_DSN

Sentry.init({
 dsn: SENTRY_DSN,
 tracesSampleRate: process.env.NODE_ENV === 'production' ? 0.1 : 0.3,
 environment: process.env.NODE_ENV,
 // ...
 // Note: if you want to override the automatic release value, do not set a
 // `release` value here - use the environment variable `SENTRY_RELEASE`, so
 // that it will also get attached to your source maps
})

Steps to Reproduce

When I import * as Sentry from @sentry/nextjs and run this

const sentryReduxEnhancer = Sentry.createReduxEnhancer({
 stateTransformer: (state: RootState) => {
 const transformedState = {
 ...state,
 auth: {
 session: {
 ...state.auth.session,
 token: null,
 },
 },
 }

 return transformedState
 },
})


export const setupStore = (preloadedState?: PreloadedState<RootState>) => {
 return configureStore({
 ...,
 enhancers: [sentryReduxEnhancer],
}

I get createReduxEnhancer is not a function error.

However, it works when I import * as Sentry from @sentry/react.

I'm thinking it's because it thinks it's in a server context so @sentry/nextjs is using @sentry/node instead of @sentry/react

Expected Result

I can us import * as Sentry from @sentry/nextjs with Sentry.createReduxEnhancer and I do not get createReduxEnhancer is not a function error.

Actual Result

TypeError: createReduxEnhancer is not a function

Ah, I can see how this is a problem. I think you are correct in the assumption that this only happens in a server context as we're not exporting it there. As a workaround for now you can check for the existence of sentryReduxEnhancer before using it. On the server, it probably won't be of much use anyways.

Thanks for the feedback @lforst!

Is this issue going to be worked on anytime soon? I would really appreciate not having to install @sentry/react as well as @sentry/nextjs as a workaround

[lforst]

It's not on our immediate backlog. PRs welcome!
