While try to add card on AnkiWeb, I get following errors

I am getting this error when trying to add card. Tried on mobile and also used different AnkiWeb account but still same error.

Are you adding the text manually or in an automated fashion? Are you trying to include JavaScript?

No, just normally.
I open the edit button from homepage, I get those errors.

It is solved now. One of my decks creating problem. I have removed the decks then it is working fine.
