Requirements:
I am building a Custom Mass Transfer Records functionality where Based on Object Name and Owner, I want to display List of Sobject Records owned by user. Once List is displayed, I want to assign all selected records to New Owner.
I have created generic object Transfer_SObject_Record__c where I have added 2 fields Type(Picklist) contains Sobject name that I want to define and Owner(Lookup:user) fields. based on these 2 field's value I want to display SObject records with Name field and Owner as a column in the List.
Problem is I am not able to pass lightning-input-field value of both fields to my controller class method.
Error Message that I see on Screen : objType & owner is undefined
Can someone please suggest how to pass lightning-input-field values as a parameter to controller class method?
Below is the code that I have written:
transferRecords.html
<template>
<lightning-card>
<div class="slds slds-p-around--medium">
