2.2.0 - JSON issues - Value should be a JSON object

[Rataplan626]

Hi,
I have several discovery rules that get input through JSON, with zabbix_trapper or external scripts. That worked fine until I updated to 2.2.0. In the what's new for 2.2.0 it states:

5.25.8 JSON validation on server

Previously, a slightly incorrect JSON could silently get accepted by the Zabbix server. Starting with Zabbix 2.2, syntax validation is performed, before parsing JSON data. Opening invalid JSON data will immediately return failure and the parsing error will be logged as warning.

Ok, that's fine with me although excactly WHAT format does zabbix expect? Even the examples given in the 2.2.0 documentation don't work for me anymore.
The error I get on the discovery-keys 'Value should be a JSON format' and the values are not processed. While I am keeping to the format the Zabbix documentation gives me, I checked with http://jsonlint.com/ and everything is fine (as well as the examples by the way). An example of my JSON string:

{
"data":[
{"{#PSU}":"psu_1.1","{#DESC}":"PSU 1, Left"},
{"{#PSU}":"psu_1.2","{#DESC}":"PSU 2, Right"}
]
}

What's wrong?

Fixed by updating to 2.2.1

I've just updated my test environment to 2.2.1 and everything works fine again with the very same JSON data. While I didn't see it mentioned in the release notes, there is probably a JSON parser bugfix in 2.2.1.

Hello, I have same problem on version 2.2.2. My script output is:

{
	"data":[

	{
		"{#SNMPJSONINDEX}":"57",
		"{#SNMPJSONDESCR}":"Port-channel1"
	}
	{
		"{#SNMPJSONINDEX}":"49",
		"{#SNMPJSONDESCR}":"GigabitEthernet1/48"
	}
	{
		"{#SNMPJSONINDEX}":"48",
		"{#SNMPJSONDESCR}":"GigabitEthernet1/47"
	}

	]
}

Some debug:

15484:20140220:110036.308 In substitute_simple_macros() data:'{HOST.HOST}'

15636:20140220:110036.307 End of zbx_vc_add_value():FAIL

But zabbix still says: value should be json object
Thanks a lot for any help.
