Error parsing yaml file:
mapping values are not allowed here
  in \"/home/antonio/Desktop/ATI/cl         


        

Answer 1

Change

application:climate-change

to

application: climate-change

The space after the colon is mandatory in yaml if you want a key-value pair. (See http://www.yaml.org/spec/1.2/spec.html#id2759963)
