Failing to send tracking events in server-side context

[quadmachine]

Hi, I'm trying to send a tracking event using your library, it's running in a Nuxt app, within SSR context, so basically Node, and window and other browser specific stuff is not available. Sending fails with error:

 ERROR  Could not send tracking event window is not defined                                                              14:22:13

  at async nuxtMiddleware (node_modules/@nuxt/server/dist/server.js:147:5)

This is my code:

const ga4mp = require('@analytics-debugger/ga4mp/dist/ga4mp.umd.js')

ga4track = ga4mp(['G-XXXXXXXXXX'], {
  user_id: undefined,
  client_id: seid,
  non_personalized_ads: true,
  debug: true,
  endpoint: process.env.SERVER_SIDE_TRACKING_COLLECTOR,
})
ga4track.setEventsParameter(
  'api_secret',
  process.env.SERVER_SIDE_TRACKING_API_KEY
)

ga4track.trackEvent('page_view')

Maybe I'm missing some configuration option, or perhaps it's a bug? Not sure, any help is appreciated.

Hi @quadmachine could you provide a simple repo to replicate this?

[quadmachine]

Sure, I've created a repo here, this is a basic Nuxt starter, only relevant stuff would be in the trackSrrPageLoad.ts here https://stackblitz.com/edit/nuxt-starter-2nzhse?file=README.md,modules%2FserverSideTracking%2Fhooks%2FtrackSrrPageLoad.ts everything else is Nuxt boilerplate.

Just run yarn dev to start the app, it will try to track the initial page load once it build but will throw with the error ReferenceError: window is not defined

Thanks for any help <3

@thyngster I've perhaps fixed the issue, in clientHints function check on line 211 doesn't break if I change from

if (window && !('navigator' in window)) {

to

if (typeof window === 'undefined') {

Perhaps I can make a MR for this?

I'm publishing a fix today

@quadmachine A fix is in place in version 0.0.5
