not able to call apex method from controller JS

Hi Team,

I am calling apex class from constrctor but while debugging i am getting below error and cursor is not going inside setCallback method. It seems it is not calling apex class. Below is code:

Error is:
his page has an error. You might just need to refresh it. Action failed: c:BeerExplorer$controller$handleCompEvents [Invalid key search] Failing descriptor: {c:BeerExplorer$controller$handleCompEvents}

Controller code:

    handleCompEvents : function(component, event, helper) {
        var searchParam=event.getParam('searchText');
        var action=component.get('search');
            var state=response.getState();
                var responseValue=response.getReturnValue();

Apex Class: 
public class BeerExplorer {

    public static List<Beer__c> search(string txtSearch)
        string likeParam='%' + txtSearch + '%';
        string query= 'select Id, Name, From Beer__c where Name Like: likeParam ';
        List<Beer__c> beerList=Database.query(query);
        return beerList;

Hi Dhiraj, schange :var action=component.get('search'); for var action=component.get('');
Use a console.log(action); to see if you are getting that right.

If it helps please mark as correct, it may help others.

Hi Agustin,

It worked at this point but it is not able to call apex class. Getting below error:

HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

Hi Dhiraj, from the console.log(action) are you getting information of the method? If not verify that you have the controller class set properly on your class.
I assume the code is incomplete and you enqueue the action to be executed, if not please do so.

If it helps please mark as correct.

Hi Agustin,
I  can see below for conole.log(action). Under which i can see method?

getCallback: ƒ ()
getError: ƒ ()
getName: ƒ ()
getParam: ƒ ()
getParams: ƒ ()
getReturnValue: ƒ ()
getState: ƒ ()
isBackground: ƒ ()
setAbortable: ƒ ()
setBackground: ƒ ()
setCallback: ƒ ()
setParam: ƒ ()
setParams: ƒ ()
setStorable: ƒ ()
toString: ƒ ()

Also under setParams i should be able to see property txtSearch but it is not available.

well, if you cant set the param it may be that searchParam does not retrieve anything.
Check with console.log(searchParam); 
If you are not getting a String then that might be the error when passing the parameter.
Try debugging that and also put a system.debug(txtSearch) on the apex method to see what you get.

use console.log(JSON.stringify(responseValue));
