CKEditor plugin validation error UI doesn't work

Hello! I need some help making the validation error show on the UI when using CKEditor with a validation, ie. maxLength in this case.

I implemented CKEditor plugin following the docs guide: Field Registering - Strapi Developer Documentation and this CKEditor in Strapi Admin with a Custom Strapi Plugin - YouTube.

It works great but there is no error in the UI. I see it console log and it returns an error when I send a mutation in GraphQL playground.

Error response in playground and console log error:

"errors": [
  "message": "ValidationError",
  "locations": [
      "line": 35,
      "column": 3
  "path": [
  "extensions": {
    "exception": {
      "data": {
        "errors": {
            "body must be at most 5 characters"

{err: s}
