Erreur à l'appel d'une API Simplicité

J’ai vérifié => utiliser getGrant().query() ne pose pas de pb non plus:

package com.simplicite.extobjects.Application;

import org.json.JSONArray;

import com.simplicite.util.exceptions.HTTPException;
import com.simplicite.util.tools.Parameters;

public class Test extends com.simplicite.webapp.services.RESTServiceExternalObject  {
	private static final long serialVersionUID = 1L;
	
	public Object get(Parameters params) throws HTTPException {
		String version = getGrant().query("select sys_value from m_system where sys_code = 'VERSION'").get(0)[0];
		return new JSONArray().put("version").put(version);
	}
}
$ curl -H 'Authorization: Bearer zHYaUibcEU6Z5n2WoyYmZOeFdtfK4XpD8qdwbT4GBhPuJZjLUY' https://testdaz40.demo.simplicite.io/api/ext/Test
["version","4.0"]
