Hi, need your help to check on this code.
This code does not give me the expected result. By right object should display all record name and submitted y should display user name. But both field should be can clock and redirect to its record 

Apex class
public with sharing class toApproved {
    @AuraEnabled(cacheable=true)
    public static list<ProcessInstanceWorkitem> getItemApprove(){
        return[select id, CreatedById,ProcessInstance.TargetObject.name,ProcessInstance.TargetObjectId,CreatedDate,CreatedBy.name from ProcessInstanceWorkitem order by CreatedDate limit 100];
    }
}

 

lwc js

import { LightningElement, wire } from 'lwc';
import toApproved from '@salesforce/apex/toApproved.getItemApprove';
const columns = [
    {label: 'CreatedDate', fieldName: 'CreatedDate' },
   
    {label: 'Object',
    fieldName:'ObjectId',
    type:'url',
    typeAttributes:{
        label:{
            fieldName:'ProcessInstance.TargetObject.Name'},
            target:'_blank'}
        },
        {label: 'Submitted By',
        fieldName:'CreatedById',
        type:'url',
        typeAttributes:{
            label:{
                fieldName:'CreatedBy.name'},
                target:'_blank'}
            }
   
];
export default class ToApproved extends LightningElement {
    availableItems;
    error;
    columns = columns;
    @wire (toApproved)
    wiredAccount({error,data}){
        if(data){
            let tempRecs = [];
            data.forEach((record)=>{
                let tempRec = Object.assign({},record);
                tempRec.ObjectId = '/'+tempRec.ProcessInstance.TargetObjectId;
                tempRec.CreatedById = '/'+tempRec.CreatedById;
                tempRecs.push(tempRec);
            });
            this.availableItems = tempRecs;
            this.error = undefined;
        }else if(error){
            this.error = error;
            this.availableItems = undefined;
        }
    }
}
