Install Zabbix Dynamic PDF Report, server 3.4.8, CentOS 7.4

The following solution is not recommended thing to do since there has been made some modifications in original Zabbix API.

Modified has been file:
/usr/share/zabbix/include/classes/api/services/CUser.php
Specifically function logout($user) has beend modified:
        public function logout($user) {
                $api_input_rules = ['type' => API_OBJECT, 'fields' => []];
                if (!CApiInputValidator::validate($api_input_rules, $user, '/', $error)) {
#                       self::exception(ZBX_API_ERROR_PARAMETERS, $error);
                }
Recommended thing is to Install Zabbix Dynamic PDF Report, Zabbix 3.0 LTS version.

But to install report on Zabbix version 3.4.8 I can execute commands like:
#!/bin/bash

#check current SELinux status
getenforce

#turn of SELinux
setenforce 0

#install vim
yum install vim -y

#download version 0.9.4
curl -L "https://drive.google.com/uc?export=download&id=0B_VNwWso1iSQcGJqamQ1dFVSWWM" -o ~/zabbix-pdf-report-0.9.4.tgz

#look where is zabbix front end directory
find / -name trigger_prototypes.php

#extract 'report' dir
tar -xvzf ~/zabbix-pdf-report-0.9.4.tgz -C /usr/share/zabbix

#move to the frontend dir
cd /usr/share/zabbix/report

#take a note what is direct ip address of server
ip a
#this will show ip address like 10.0.2.15

#enter credentials
vim config.inc.php
#$z_server       = 'http://10.0.2.15/zabbix/';
#$z_user         = 'Admin';
#$z_pass         = 'zabbix';

#fix message
#Unable to logout: Array ( [code] => -32602 [message] => Invalid params. [data] => Invalid parameter "/": unexpected parameter "user". ) 

#look just below logout($user) function
cd /usr/share/zabbix/include/classes/api/services
#show some output of active configuration
grep -n -A5 "public function logout" CUser.php
#backup configuration
cp CUser.php ~
#calculate line to comment out
ln=$(grep -n -A5 "public function logout" CUser.php | grep ZBX_API_ERROR_PARAMETERS | egrep -o "^[0-9]+")
#echo line number
echo "$ln"
#uncomment line
sed -i "$ln {s/^/#/}" CUser.php
#show what has been commented
grep -n -A5 "public function logout" CUser.php
