I get "Authentication Error: Please check your token! error" message.

I used token_v2 value in F12 > Application > Storage > Cookies on Chrome.

But it says "Authentication Error: Please check your token! error". However, when I tried, getAllHTML() method seems working fine. But it gives unexpected JSON data.

Why does it show the message? What's the meaning of that?

Could you please provide a code example?
