I am getting the above error when I try to send data to salesforce org using node and express. How do I resolve this?

Here is my code

Whenever I try to create a lightning app, I get the following error. 


I try to insert an image for my app. But am unable to do so. 

I am opening the app as an admin. 
I have no idea why I can't select the fields. I can read/write on them. 

How do I add the user in my XML file. 

I have a scenario where I need to check if a file has been added to a custom object record. If a file is already present, then the user should not be able to upload more files. Else, the user should be able to upload files.

The data is stored in this.imageUrl and this.itemList. I want the itemList to have an additional key value pair with key as 'url' and value as the data in imageUrl

The data in itemsList = [
{Item_Name__c: 'Chicken Momo', Price__c: 2.5, Id: 'a0C5j000000JiOIEA0'},
{Item_Name__c: 'Veg Momo', Price__c: 1.5, Id: 'a0C5j000000JiOHEA0'}
]

The data in imageUrl = ['/sfc/servlet.shepherd/document/download/0695j000007jP4qAAE', '/sfc/servlet.shepherd/document/download/0695j000007igi6AAA']

I want something like
temsList = [
{Item_Name__c: 'Chicken Momo', Price__c: 2.5, Id: 'a0C5j000000JiOIEA0',
url:'/sfc/servlet.shepherd/document/download/0695j000007jP4qAAE'},
{Item_Name__c: 'Veg Momo', Price__c: 1.5, Id: 'a0C5j000000JiOHEA0',
url:'/sfc/servlet.shepherd/document/download/0695j000007igi6AAA'}
]
 

I was able to create new LWC component, deploy source to org before. But after I closed the project and reopend it, I can no longer do any of those. How do I resolve this?

I am trying to load images that I have uploaded as a zip file on my org Static Resources. However, the images do not load. Why is this happening?
My Code
import { LightningElement } from 'lwc';
import CAROUSEL_IMAGES from '@salesforce/resourceUrl/carousel';
export default class CustomCarouselWrapper extends LightningElement {
slides = [
{
image : `${CAROUSEL_IMAGES}/carousel/Naruto.jpeg`
},
{
image : `${CAROUSEL_IMAGES}/carousel/Luffy.jpeg`
},
{
image : `${CAROUSEL_IMAGES}/carousel/DragonBallZ.jpg`
}
]

}

Why is this happening and how do I solve it?

When I press the Add To Cart button, if I am logged in as system admin, the button works.But when I am logged in as a User, the same button does not work.
Why is this error occuring, and how to I resolve it?

I am trying to update the value of my object elements whenever one of the object is deleted. However, I always get the Uncaught ReferenceError: i is not defined error on my console. 

Here is my code 

deleteTask(event) {

this.todoTasks = this.todoTasks.filter(task => task.id !== event.target.name);
this.updateId();
console.log(this.todoTasks);
}
updateId(){
for(i=1; i<=this.todoTasks.length; i++){
this.todoTasks[i-1].id = i;
}
}

I see only delete - no edit. Is this not possible or hidden somehow?
