Hi @sikhaooapp, Ah I see, thank you for clarifying that you’re running into this error on your server. It sounds like this might be an issue with your server configuration. Can you ensure that you have CORS policies allowed? While this is a thread for vue.js, it sounds like you could be running into a similar issue: > > > Version > 4.3.1 > Environment info > We're sorry but work doesn't work properly without JavaScript enabled. Please enable it to continue. > Steps to reproduce > I created a VueJS... Let me know if this helps, Will ---
