There are some spell corrections in the request body employess changed to employee even after that I am getting action null in response.

Hi,

I have data models like a department with a list of employees and an Action.
There are conditions like if employee age is greater than 35 then set is eligible true in Action.
If employee skill is "JAVA" then set skill true in Action and if the above 2 conditions are true then set both fields to true.
I did create a Guided decision table from the workbench then I could see rules like the below source.

package com.myspace.organizationrules;

//from row number: 1
rule "Row 1 OrgGuidedDecisions"
salience 9
ruleflow-group "orgRule"
dialect "mvel"
when
$d : Department( )
(Employee( age > ( 35 ) ) from $d.employees)
then
Action action = new Action();
action.setIsEligible(true);
$d.setAction(action);
update($d);
end

//from row number: 2
rule "Row 2 OrgGuidedDecisions"
salience 8
ruleflow-group "orgRule"
dialect "mvel"
when
$d1 : Department( )
(Employee( skill == ( "JAVA" ) ) from $d1.employees)
then
Action action = new Action();
action.setIsSkill(true);
$d1.setAction(action);
update($d1);
end

//from row number: 3
rule "Row 3 OrgGuidedDecisions"
salience 10
ruleflow-group "orgRule"
dialect "mvel"
when
$d2 : Department( )
(Employee( age > ( 35 ) , skill == ( "JAVA" ) ) from $d2.employees)
then
Action action = new Action();
action.setIsEligible(true);
action.setIsSkill(true);
$d2.setAction(action);
update($d2);
end

I did deploy changes to Kie-Server and tried to execute the above rules with API like below.

--header 'Authorization: Basic d2JhZG1pbjp3YmFkbWlu' \
--header 'Content-Type: application/json' \
--data-raw '{
    "commands": [
        {
            "insert": {
                "out-identifier": "orgRule",
                "object": {
                    "Department": {
                        "employess": [
                            {
                                "id": 1,
                                "name": "Santhosh",
                                "age": 30,
                                "skill": "JAVA"
                            },
                            {
                                "id": 2,
                                "name": "Sri",
                                "age": 36,
                                "skill": "JAVA"
                            },
                            {
                                "id": 2,
                                "name": "Vas",
                                "age": 36,
                                "skill": "PYTHON"
                            },
                            {
                                "id": 2,
                                "name": "Vasu",
                                "age": 34,
                                "skill": "PYTHON"
                            }
                        ]
                    }
                },
                "return-object": true
            }
        },
        {
            "fire-all-rules": {
                "max": "1",
                "out-identifier": "orgRule"
            }
        }
    ]
}'

response is: 
{
  "type" : "SUCCESS",
  "msg" : "Container OrganizationRules_1.0.0-SNAPSHOT successfully called.",
  "result" : {
    "execution-results" : {
      "results" : [ {
        "value" : 0,
        "key" : "orgRule"
      } ],
      "facts" : [ {
        "value" : {"org.drools.core.common.DefaultFactHandle":{
  "external-form" : "0:1:1428226676:1428226676:1:DEFAULT:NON_TRAIT:com.myspace.organizationrules.Department"
}},
        "key" : "orgRule"
      } ]
    }
  }
}

but rules are not executing. Can someone help me with this?

Thank you!

It does not look like you have activated the ruleflow group. If you are using a ruleflow, you need to start it.
