Sunil Nandipati Error during init [Assertion Failed!: Unknown controller action 'getExpenses' : undefined]
I am trying the Lightning ExpenseTracker app.
During Step 3 - Load the Expense Data, i am running into this error.
"This page has an error. You might just need to refresh it. Error during init [Assertion Failed!: Unknown controller action 'getExpenses' : undefined]"
Has anybody experienced the same?

public with sharing class ExpenseController {

// Perform isAccessible() check here
return [SELECT Id, Name, Amount__c, Client__c, Date__c,
Reimbursed__c, CreatedDate FROM Expense__c];

}
This could be due to 3 equivalent to opeartors in if condition. Try to remove one and test.
if (component.isValid() && state === "SUCCESS") {

Brahma
it's happen becuse of your helper function name is "getExpenses" and your apex class method name also "getExpenses" so its get confuse between them
so change you helper method name
i hope it helps you.
Let me inform if it helps you and kindly mark it best answer if it helps you so it make proper soltuions for others
thanks
