wso2 CEP error in event list - wso2

Question

The post seems long but is is only because of data (samples and errors).
I am trying to make a bucket mocking the buildFailed sample in cep 2.1.0. (This sample works).
I have created my own stream and my own sample data.
Yet it seams that the input handler of cep his having trouble with my events.
So far I have not found the issue.
The stream def :
{
"name":"eu.ima.event.stream",
"version": "1.2.0",
"nickName": "poc sample",
"description": "poc sample stream",
"metaData":[
{
"name":"host",
"type":"string"
}
],
"correlationData":[
{
"name":"processus",
"type":"string"
},
{
"name":"flux",
"type":"string"
},
{
"name":"reference",
"type":"string"
}
],
"payloadData":[
{
"name":"timestamp",
"type":"string"
},
{ "name":"code",
"type":"string"
},
{
"name":"category",
"type":"string"
},
{
"name":"msg",
"type":"string"
}
]
}
The events data :
[
{
"metaData" : ["192.168.1.2"] ,
"correlationData" : ["PSOR", "Appli2", "Ref-1"] ,
"payloadData" : ["1363700128138496600", "6", "BIZ", "6"]
}
,
{
"metaData" : ["192.168.1.2"] ,
"correlationData" : ["PSOR", "Appli2", "Ref-0"] ,
"payloadData" : ["1363700126353394500", "6", "BIZ", "6"]
}
,
{
"metaData" : ["192.168.1.2"] ,
"correlationData" : ["PSOR", "Appli2", "Ref-3"] ,
"payloadData" : ["1363700131731702100", "6", "BIZ", "6"]
}
,
{
"metaData" : ["192.168.1.2"] ,
"correlationData" : ["PSOR", "Appli2", "Ref-2"] ,
"payloadData" : ["1363700129894597000", "6", "BIZ", "6"]
}
,
{
"metaData" : ["192.168.1.2"] ,
"correlationData" : ["PSOR", "Appli2", "Ref-4"] ,
"payloadData" : ["1363700133472801700", "6", "BIZ", "6"]
}
]
When I send the streamdef, no error and no log except the admin connected
We might need more feedback here. I use the curl post command.
When I send the events I have errors :

Please anyone, do you have any hints ?
I really need this to keep on with my Proof of concept CEP Project.

I have gone through the details that you given above... But without the bucket configuration and complete error log it is hard to say what went wrong... But I have checked the stream definition and events that you have given above... It is working perfectly without any issue... I hope that you might made simple mistake when creating the bucket... Here I am sharing the bucket xml that I have created (note: change the email address in the output topic)
events json : link [1]
stream json : link [2]
bucket xml : link [3]
curl command for Stream :
curl -k --user admin:admin https://localhost:9443/datareceiver/1.0.0/streams/ --data #streamdefn2.json -H "Accept: application/json" -H "Content-type: application/json" -X POST
curl command for events :
curl -k --user admin:admin https://localhost:9443/datareceiver/1.0.0/stream/eu.ima.event.stream/1.2.0/ --data #events2.json -H "Accept: application/json" -H "Content-type: application/json" -X POST
