Won't render pdf #42

Grails version: 3.3.1 Rendering plugin: 2.0.3
To duplicate, create a Grails project with one class called Person with three String attributes: name, surname, emailAddress. At the bottom of the show view I have this:
<g:link class="edit" action="pdfThis" resource="${this.person}">Pdf This</g:link>
The method in the controller is this:

def pdfThis(Long id){
        def person = Person.get(id)
        if(person){
            pdfRenderingService.render(template: "/templates/pdf/person", model: [person: person], controller: "person", response) // this is line 105
        }
    }

I notice that def pdfRenderingService does not work anymore. One has to have:
grails.plugins.rendering.pdf.PdfRenderingService pdfRenderingService in the controller.

This is the template, called _person.gsp, in views/templates/pdf/

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
 <html>
    <head>
        <title>A PDF Document</title>
    </head>
    <body>
        <h1>${person?.name} ${person?.surname}</h1>
        <p>
            Your email address: ${person?.emailAddress}
        </p>
    </body>
 </html>

These are the exceptions:

I have no idea what is null and why it is null. Everything I am responsible for is there and is not null.

I have gone directly to the IText and Flying Saucer libraries and everything works. Rendering was removed as a dependency. It was simpler than I had thought.

did you have any solution to this problem?

I had to add the following line to build.gradle:

runtime "org.springframework:spring-test:4.2.1.RELEASE"
