We're sorry but sf doesn't work properly without JavaScript enabled. Please enable it to continue

I have a Vuejs app that makes an Axios call. I Dockerized it and used digitalocean to serve it to the cloud. App is working but after any axios call, i am getting "We're sorry but sf doesn't work properly without JavaScript enabled. Please enable it to continue." as response. -I have tried changing the port from 8080 to 8081, running the app on incognito browser tab, changing "baseUrl" with "baseURL" and in front-end docker file i was installing libraries with npm, i also tried to use yarn but i still have this issue.

Is there any more idea about how to fix it ?

main.js file

    createApp(App)
  .use(store)
  .use(vue3GoogleLogin, {
    clientId:
      "******",
  })
  .component("font-awesome-icon", FontAwesomeIcon)
  .component("MazBtn", MazBtn)
  .component("MazInput", MazInput)
  .component("MazPhoneNumberInput", MazPhoneNumberInput)
  .component("Datepicker", Datepicker)
  // .component("VueGlide", VueGlide)
  .use(router)
  .mount("#app");
