UserParameter is parsed wrongly

[IteaAgain]

Hello,

i have a template and some easy scripts for doing RAID checks on multiple machines.
the Problem is related in a UserParameter that does nothing more then a "cat" on a text-file

in Zabbix i got a "Unsupported Item" and a "Permission denied"

UserParameter=RAIDVolume.json,/usr/bin/cat /home/iteanova/RAIDVolumes.json

this is for a discovery-rule and gives just the hardcoded list of RAID Volumes to zabbix.

Zabbix-Server is Version is 3.0.4.stable
this works fine on debian (Zabbix 3.0.7), but not on CentOS (Zabbix 4.2.8)
result in logfile on CentOS

6988:20200429:105415.860 Requested [RAIDVolume.json]
6988:20200429:105415.860 In zbx_popen() command:'/usr/bin/cat /home/iteanova/RAIDVolumes.json'
6988:20200429:105415.863 EXECUTE_STR() command:'/usr/bin/cat /home/iteanova/RAIDVolumes.json' len:64 cmd_result:'/usr/bin/cat: /home/'
6988:20200429:105415.863 Sending back [/usr/bin/cat: /home/iteanova/RAIDVolumes.json: Permission denied]

result in debian

30841:20200428:173905.739 Requested [RAIDVolume.json]
30841:20200428:173905.739 In zbx_popen() command:'cat /home/iteanova/RAIDVolumes.json.log'
30841:20200428:173905.742 EXECUTE_STR() command:'cat /home/iteanova/RAIDVolumes.json.log' len:57 cmd_result:'{
{ "{#RAIDV}":"md0"},
{ "{#RAIDV}":"md127"}

the permissions of the json-file are the same on both systems. Zabbix User can read.

The problem seems to be realted to the parsing of the "/usr/bin/cat FILE" which is in debian executed while in CentOS is given back a "/usr/bin/cat: file"

Can someone help me? Is this a bug?

on the CentOS machine with the problem i got

[iteanova@iteanova004 ~]$ zabbix_agentd -t RAIDVolume.json
RAIDVolume.json                               [t|{
"data":[
{ "{#RAIDV}":"md124"},
{ "{#RAIDV}":"md125"},
{ "{#RAIDV}":"md126"},
{ "{#RAIDV}":"md127"}
]
}]

but zabbix shows me a

Invalid discovery rule value: cannot parse as a valid JSON object: invalid object format, expected opening character '{' or '[' at: '/usr/bin/cat: /home/iteanova/RAIDVolumes.json.log: Permission denied'

i really don't get it :-(
The zabbix-server logs shows me nothing when i do a

cat  /var/log/zabbix/zabbix_server.log | grep -i raid

, even it shows me all other items that are called from the machine.
