Hi. Has anyone able to successfully use GB in Nuxt 2? I'm having an issue where I can see the features in localStorage but no matter what I do, getFeatureValue and isOn is not working with the feature key. Even with the chrome extension, it is saying that there is no feature or experiment.

I know it works with Nuxt
seems like its making the network call?
could there be two instances somehow?

@breezy-king-73167 I am having some issues with a feature not working in Chrome. When you say “found it”, what was the cause of your issue / how did you fix it? Thanks

Apparently, you have to load the features first even though it was stored already in local storage. Add this to your plugin.
Copy code
await gb.loadFeatures({ autoRefresh: true });

In case this can help, I created this simple boilerplate for Nuxt 2 and GA4/GTAG for our POC.
Copy code
import { GrowthBook } from '@growthbook/growthbook'

export default ({ env }, inject) => {
  let growthBook = null
  /**
   * For initializing Growthbook
   * @returns (null/Growthbook) Returns GrowthBook or null
   */
  const initGrowthBook = async function () {
    /* Prevent reinitializing Growthbook */
    if (growthBook) {
      return growthBook
    }

    /* Initialize Growthbook */
    growthBook = new GrowthBook({
      apiHost: env.GROWTHBOOK_API_HOST,
      clientKey: env.GROWTHBOOK_API_KEY,
      enableDevMode: env.NODE_ENV === 'development',
      trackingCallback: (experiment, result) => {
        // track using GA4
        if ("gtag" in window) {
          this.$gtag.query("event", "experiment_viewed", {
            event_category: "experiment",
            experiment_id: experiment.key,
            variation_id: result.variationId,
          })
        } else {
          console.warn("no gtag")
        }
      }
    })

    //Set user attributes
    await this.$gtag.query('get', env.GA4_TRACKING_ID, 'client_id', (client_id)=>{
      growthBook.setAttributes({
        country: 'france',
        id: client_id,
      })
    })

    /* Load Growthbook features */
    try {
      await growthBook.loadFeatures({
        autoRefresh: true,
        timeout: 2000,
      })

      return growthBook
    } catch (error) {
      console.error('Failed to load features from GrowthBook', error)
      return null
    }
  }

  inject('initGrowthBook', initGrowthBook)

@breezy-king-73167 I try to use this but it didn't work, it said
loadFeatures
is not a function, did you ever experience it?
