Unable to display posts list in Mars theme

Hi, is anyone able to help or offer advice in where I am going wrong?

I have used the Mars theme to create my own theme, so maybe I have changed something that Iā€™m not aware off, but for some reason I canā€™t seem to get the posts list to display posts anymore anymore. Instead I get an error stating ā€œCannot read property ā€˜titleā€™ of undefinedā€.

I have set my postsPage to /news in settings and I can see this and the posts when I console.log(frontity.state);

I donā€™t think I have changed anything in the Mars components.

Any help is greatly appreciated.
