Exeption error after upgrading to magento 2.2.2

Hi,

 

I have been building a theme for my website, I was using magento 2.1.

We decided to upgrade magento to the latest version but my blocks that I have built started to give me errors.

 

this is the error page I am getting, but I cannot figure out what could cause this problem:

1 exception(s):

Re: Exeption error after upgrading to magento 2.2.2

I managed to solve the problem. the solution was to name the xml file found in view\frontend\layout\ according to this format:

{router_id}_{controller_name}_{action_name}.xml

then it worked fine.
