Calling flow from Lightning component and passing variable

Hi,
I have written a lightning component and calling a flow from this. It works fine except there is one problem. I am able to pass the record id as a flow variable since that is the flow input variable but there is one more field inside the flow and the flow has a decision node based on that field. If i pass only the Id, the other field inside the flow doenst seem to get the field value even though the field from the same object.
If this is the case how can i pass other field value to the flow along with the id ?
Below are my component and controller:  
<aura:component implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,force:lightningQuickAction" access="global" >
    <aura:attribute name="claim" type="Claim__c"/>
    <aura:attribute name="claimId" type="Id"/>
    <force:recordData aura:id="claimRecordLoader" recordId="{!v.recordId}" fields="Submit_to_TPA__c"
                      targetRecord="{!v.claim}" />
    <aura:handler name="init" value="{!this}" action="{!c.init}" />
    <lightning:flow aura:id="flowData"/>
</aura:component>
  
({
    init : function (component) {
        // Find the component whose aura:id is "flowData"
        var flow = component.find("flowData");
        var inputVariables = [
            {
                name : "ClaimIdVar",
                type : "SObject",
                value : { "Id" : component.get("v.recordId")}
                //value : component.get("v.recordId")
            }
        ];
        // In that component, start your flow. Reference the flow's Unique Name.
        flow.startFlow("SubmitToTPA", inputVariables );
    },
    
})

hi Nehashri320 ,

for do this, you have need to query the record with there fields using currentrecordId in doInit function: 

for reference : 
  create a apex controller :
  
public class flowCtrl{
  @AuraEnabled 
    public static objectApiName__c fetchRecord(string recId){
        return [select id,Name,yourFieldApiName__c from objectApiName__c  WHERE id =: recId] ;
    }
}

update in js controller : 
({
    init : function (component) {
         var action = component.get("c.fetchRecord");
          action.setParams({
            'recId': component.get("v.recordId")
          });
        action.setCallback(this, function(response) {
            var state = response.getState();
            if (state === "SUCCESS") {
                var storeResponse = response.getReturnValue();
           // Find the component whose aura:id is "flowData"
           var flow = component.find("flowData");
           var inputVariables = [
             {
                name : "ClaimIdVar",
                type : "SObject",
                value : { 
				       "Id" : component.get("v.recordId"),
					   "otherVarFieldName__c" : storeResponse.yourFieldApiName__c
					   }
                //value : component.get("v.recordId")
              }
           ];
           // In that component, start your flow. Reference the flow's Unique Name.
           flow.startFlow("SubmitToTPA", inputVariables );
		
            }
        });
		
    $A.enqueueAction(action);
    },
    
})

update in component : add controller to component

<aura:component controller="flowCtrl" implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,force:lightningQuickAction" access="global" >

Thank you for your reply. Will definetly be helpful to me. I have solved the issue. Actually, I wasn’t testing correctly. But out of curiosity, Can I use lightning data service to do this instead of Apex class?

yes LDS also a good option for load value without apex, but LDS have own limitations right now so i recommend above method. it's easy and stable and we have create sample post on LDS you can take a reference from there :

Thank you @piyush_soni

I would like to add one more question here or Shall I start a new thread? I followed your steps and it works great except for when some field value is null. In the name, type, value pair If a field value is null, it throws an error. How can I check for this? If it is null. Thank you in advance! [cid:image001.png@01D35EF2.B34F1F80]

Just adding Code Snippet in case you have multiple variables to send to flow

 var inputVariables = [{name:'caseIntId', type:'String', value:component.get("v.caseInteractionId")}, 
                                          {name:'userId', type:'String', value:component.get("v.userId")}];
                    flow.startFlow(flowId, inputVariables);
