I'm a newbie for APEX and I'm trying to redeploy a fix for a former APEX trigger we had already deployed to production.  When I try to deploy it, I get it shows Code Coverage as 64% (9/14) and won't let me deploy.  Can someone please let me know what I'm doing wrong?

Apex Trigger:

trigger UpdatePricing on OpportunityLineItem (before insert, before update) {


Map<String, List<Volume_Discount__c>> PricingMap = new Map<String, List<Volume_Discount__c>>();
for(Volume_Discount__c  P : [SELECT ID,Minimum_Quantity__c,Product__c,Price_Book__c  FROM Volume_Discount__c ORDER BY Minimum_Quantity__c])
{
  if(PricingMap.KeySet().contains(P.Product__c+'|'+P.Price_Book__c))
  {   
     PricingMap.get(P.Product__c+'|'+P.Price_Book__c).add(P);
  }
  else
  {
     PricingMap.put(P.Product__c+'|'+P.Price_Book__c,new List<Volume_Discount__c> {P});
  }
}


for(OpportunityLineItem  oli : Trigger.new)
{
oli.Volume_Discount__c = null;
if(PricingMap.KeySet().contains(oli.Product2Id+'|'+oli.Opportuity_PriceBook2__c) && oli.ProductAndPriceBookActive__c)
{
    for(Volume_Discount__c P : PricingMap.get(oli.Product2Id+'|'+oli.Opportuity_PriceBook2__c))
    {
        if(oli.quantity >= P.Minimum_Quantity__c)
        {
           oli.Volume_Discount__c = P.ID;
        }
    }
}

}

I am trying to create a quick Action that calls the flow and lightning component to create a record as suggested in the blog (https://thewizardnews.com/2018/08/02/url-hack-functionality-lightning/) here. I need to create a record of custom object from Opportunity record , using the Quick action as suggested in the blog. I created a flow like below with the Action which calls the lightning component createAXProjectRecords 

And the Lightning component is like
createAXProjectRecords.cmp

<aura:component implements="lightning:availableForFlowActions"> <aura:attribute name="InputContactID" type="String" /> <aura:attribute name="InputAccountID" type="String" /> </aura:component>

createAXProjectRecords.design

<design:component> <design:attribute name="InputContactID" /> <design:attribute name="InputAccountID" /> </design:component>

createAXProjectRecordsController.js

({ invoke : function(component, event, helper){ var ContactID = component.get("v.InputContactID"); var AccountID = component.get("v.InputAccountID"); var createRecordEvent = $A.get("e.force:createRecord"); createRecordEvent.setParams({ "entityApiName": "AX_Project__c", "defaultFieldValues": { 'Contact__c' : ContactID, 'Account__c': AccountID } }); createRecordEvent.fire(); } })

When I try to click on the Quick Action on the Opportunity record I get  

Can anyone please suggest me what I am missing here.
