Lazy loading local resource works, but it keeps calling the function even after the resource is loaded

🐛 Bug Report

To Reproduce

I can successfully lazy load certain resources locally using the callback mechanism documented. However, the function seems to get called again (to load the resources again) even though I have already loaded them. I am using vite (not webpack) so the solution is a bit clunky (vite does not allow interpolated strings on a dynamic import).

ResourcesToBackend(async (lang, ns, cb) => {
          if (lang === 'en' && [foo', 'bar'].includes(ns)) {
              try {
                const { default: resources } =
                  ns === 'foo'
                    ? await import('@core/i18n/foo.json')
                    : await import('@core/i18n/bar.json')
                cb(null, resources)
              } catch (err) {
                console.error('Failed to load bundled resources', err)
                cb(err as Error, null)
              }
            } else {
              cb(null, null)
            }
        }),
      ]

Expected behavior

Despite successfully loading the resources here with cb(null, resources) the function still gets called again for the same language and namespace - as if it is not loaded. However the translations work fine.

Your Environment

• runtime version: node 18
• i18next version: i.e. 23.5.1
• os: Mac

Please provide a complete but minimal reproducible exampe. i18next-resources-to-backend does not trigger any loading, it's all controlled by i18next core

I found out why. The behaviour is correct. I will close this.
