issue with "Use Redis in the Kyma Runtime to Store and Retrieve Data" tutorial

[hokandil]

the cache-order function yaml file from github on The tutorial "Use Redis in the Kyma Runtime to Store and Retrieve Data" is giving error whenever I try to deploy it

I had to do some changes in order to make it run.

Hi Hossam,

Your Central gateway URL is wrong. You should take it from integration -> applications -> API (in Kyma dashboard)
