I currently have the aura component makes a call to the server (apex class) and updates the record, I post a toast on the page if any error that happens while updating the record like below

  var action = c.get("c.updateCheck");
    action.setParams({caseId: c.get('v.recordId'), Status: StatusSel});
    action.setCallback(this, result => {
        switch (result.getState()) {
        case "SUCCESS":
        type: 'success',
        message: 'Case is closed!',
        mode: 'pester'
    $A.util.addClass(spinner, "slds-hide");
    var errors = result.getError();
    if (errors) {
        if (errors[0] && errors[0].message) {
                type: 'error',
                mode: 'pester',
                message: errors[0].message }).fire();  

In the above code I get the exact error on the update event like

I am trying to use the lightning data service here instead of the apex class and try to capture the error like below on the onerror action.

handleError: function(component, event, helper) {
    var error = event.getParams();
    var errorMessage = event.getParam("message");
        type: 'error',
        mode: 'pester',
        message: errorMessage.message }).fire();  

But I see the toast like

How can I show the toast as exactly as it shows while using the apex call. Am I missing anything here. Any help is greatly appreciated


you should use event.getParam('detail') instead of event.getParams() in my scenario i added validation rule on contact object firstname field.


        <lightning:inputField fieldName="FirstName" />
        <lightning:inputField fieldName="LastName" />
        <lightning:inputField fieldName="Email" />

        <div class="slds-m-top_medium">
            <lightning:button variant="brand" class="slds-align_absolute-center" type="submit" name="save" label="Save" />


handleError: function(component,event,helper){
    var errordetails = event.getParam('detail');
    console.log("errordetails", JSON.stringify(errordetails));
    var toastEvent = $A.get("e.force:showToast");
        type: 'error',
        mode: 'pester',
        message: JSON.stringify(errordetails)

  • I dont see anything on the toast when I change from var errorMessage = event.getParam("message"); to detail like var errorMessage = event.getParam('detail'); I see an empty toast and if I stringify the JSON I see ` ]}},"error":]}}},"headers":}}` – user81642 Jul 24 '20 at 17:16
  • what is coming in to console.log("errorMessage ", JSON.stringify(errorMessage )); ? – sdandamud1 Jul 24 '20 at 17:26
