grails 5 spring security 5 403 error page is not shown

Question

I am using grails 5.2.5 and spring security 5.6.0. When a 403 is occurred then the access deny message is written in the browser document.I want to show a 403 specific view page.But it is not working. My code as below:

URL mapping:

'403'(controller: 'error', action: 'denied')

Error controller denied action:

def denied() {
    render(view: '/error/denied', model: [errorMessage: "403 sample error"])
}

denies view page under error directory:

<section class="content">
        <h1 style="color: red">${errorMessage}</h1>
    </section>

But it does not work. Instead it writes to browser the following message:

Access to localhost was denied 
You don't have authorization to view this page.
HTTP ERROR 403

grails.plugin.springsecurity.logout.postOnly = false    // just for test

I find a workout by this stackoverflow.com link : configure in application.groovy.

I had to add this line in application.groovy file :

grails.plugin.springsecurity.adh.errorPage = null
