Apex 'variable does not exist'

Question

I encountered an issue, as I want to access a property of an object I'm passing from a lwc to an apex method, like this:

valuesObj.ml_id = this.sfItem.id;
this.itemObj = valuesObj;

and then:

processItemEdit( {item : this.itemObj} ).then(r => {
     console.log('r', r);
});

This is the apex method:

@AuraEnabled
public static void processItemEdit(CsvItem item){
    List<CsvItem> items = new List<CsvItem>();
    String seller_id = String.valueOf(item.ml_id);
    Seller_Setting__c setting = SellerSettingDataManager.getSetting(seller_id);
    setting = BatchApexListItems.getSetting(setting.id);
    items.add(item);
    BatchApexListItems.processItemsCsv(items, setting);
}

For some reason, apex throws an error when I try to deploy, saying the variable 'item.ml_id' does not exist, when it is defined in the first line of code I included here. What is going on?

Answer 1

As I see you have just created the object CsvItem on the client side. But when the object is passed to server side, i.e. Apex, you need same properties in Apex class defined as 'CsvItem'

For eg:

public class CsvItem{

    public String ml_id {get ; set; }
}
