Custom field validation is not working in Gutenberg Editor

[kalpanasharma19]

In Latest Version 5.0, Gutenberg doesn't allow validation with WCK plugin. Lets create a custom post type and add the custom field with required.

And when we add custom post type with the custom field, required field doesn't shows validation.

This validation is working with old editor.

Gutenberg is still in active development stage and not everything is readily available yet.

Validating custom fields or metaboxes directly from Gutenberg to my knowledge not fully implemented properly till date.

So at this stage my suggestion would be to continue with Classic Editor plugin specially when you are dealing with custom fields.
