var DB_ID = "your_DATABASE_ID_here"; 
var DB_FIELD = "your_DB_FIELD_here";

let myRequestResult = get_BackendData(DB_ID, DB_FIELD); 
console.log(myRequestResult);
 

export function get_BackendData(DB_ID, DB_FIELD){
    return wixData.get(DB_ID, DB_FIELD) 
    .then( (res) => {console.log("Res: ", res);
        let items = res; console.log("Items: ", items); 
	return(items);
    }).catch((err)=>{console.log("ERROR: ", err); return(err);}); 
}

Why it is an EXPORT function?
-Is your function not located on the same page? Backend?
