Wix code SDK error: missing _id

I’m having troubles setting the data for a repeater.
I got this error: Wix code SDK error: Each item in the items array must have a member named _id which contains a unique value identifying the item.

I checked this answer in the forum, but I don’t understand what I’m missing.

Any idea what’s the issue?

Hi,

can you also share the code you are using to set the items to repeater?

Thanks!

Sure.

This is it:

export function retrieveDataButton_click(event, $w) {
	
	getPropertiesBundle()
		.then(json => {
			
			console.log(json);			
			
			var propertyBundle = json;
			
			$w("#repeater1").data = propertyBundle;
			
			for(let i=1;i<=propertyBundle.lenght;i++) {
  				$w("#repeaterPropertyTitle").text = propertyBundle[i].property.title;
  				$w("#repeaterPropertyAddress").text = propertyBundle[i].property.snippet;
			};
	
		});
}

I must add that I recover the data using wix http-function and get a json from a web-service:

import {fetch} from 'wix-fetch';  

export function getPropertiesBundle() {
  const url = 'http://myCensoredUrl
  console.log("Url: " + url);

return fetch(url, {method: 'get'})
  .then(response => response.json());
}

Had the same issue, fixed it.

For those wondering, the check that wix does for a missing “_id” property is not explicit. Probably done with a == instead of ===. Any _id of “0” is treated as the same as null or undefined . Adding a prefix to the _id will resolve the issue. Do note that property _id must be of type string .
