Error /increment/{value}

Every path works except the /increment/{value}
When I try to go to http://devsecops-liverpool.eastus.cloudapp.azure.com:30012/increment/50 I get the following error:

# Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
