Hi!

Shopware backend extjs question. Shopware 5.4.6 version

I have task to implement button on plugin config window which will send request on backend controller. So I implemented button and wrote code to execute ajax:

```
            Connect
            Verbinde
            Connect

```

And when I click to button I get status 500 with message in apache log:

Call to undefined method Shopware\_Proxies\_ShopwareControllersBackendEtsyUserDataProxy::setFront()

So, is there proper way to write this request or I misunderstood something? Or it is a bug?

**Controllers** Folder is reserved for the old controller system. Just name your folder to **„Controller“** or move this controller to new „controller“ folder and it will work
