Text length ValidationError in STRAPI with CKEditor

I am using STRAPI with custom rich text editor. I setup from this docs

Now If I write more than 234 word I gives ValidationError in console. I am trying to increase max text limit but I am not sure it is possible or not and from where we can increase word limit.

Here is I am using STRAPI version v3.6.2
