I have a wrapper class in my apex controller.
global class variableDTO { @AuraEnabled public String bkImgURL { get; set; } @AuraEnabled public List<String> monthListBefore {get; set;} }
And I am trying to to access the monthListBefore list in LWC. My code is below.
@track background; @track MonthList; @wire(getAllDTOs) wrappers ({ error, data }) { if(data) { this.objects = data; this.background = data[0].bkImgURL; this.MonthList = data[0].MonthListBefore; console.log(this.background ); console.log(this.MonthList ); } else { this.error = error; } }Here I got value for this.background but I got undefined for this.MonthList. Is there anything wrong in my code?
I got value MonthListBefore in json when I debug.
"monthListBefore":[ "Avr", "Mai", "Jui", "Jui", "Aoû", "Sep", "Oct", "Nov", "Déc" ],
Thank you.
Change your track like below,
MonthList is declared by initialising to null. So even before wired function gets back the data, the template is trying to display data[0].MonthList which is throwing error.
hope this will help you.
Thanks

Here the issue was I am using "monthListBefore" in controller But in javascript I am using "MonthListBefore".Both are different. Its case sensitive.
Thank You for your help!
