Retry query for wix

retry.js

//This is an answer for the following Wix post https://www.wix.com/corvid/forum/community-discussion/backend-function-call-timeout
// Code hasn't been tested and might require ajustment. Plz comment below

const TIMEOUT_CODE= '...'; // error message from wix server
const RETRY_MAX = 3;

// Note that this will work as long as your frontend Promise does not expire.
// It might be safer to have the retry on the frontend side.
function retryQuery(query, iteration=0){
	return query.find().catch(reason => {
		if(reason === TIMEOUT_CODE) {
			if(iteration === RETRY_MAX){
				console.error('retried '+RETRY_MAX+' times and failed');
				throw reason;
			}
			return retryQuery(query, ++iteration);
		}
			
		//Not a timeout, throw back the error
		throw reason;
	})
}

//Usage
function get_my_product(prodId) {
	let query =  wixData.query("products").eq("productId", prodId).limit(1);
	
	return retryQuery(query)
		.then((results) => {
			let prodItems = results.items;
        		return (prodItems[0]);
        	}).catch(reason => {
			let errorMsg = error.message;
			myLog("My Product Query Error Msg/Code = " + errorMsg)
		});
