Just sent a post request with postman. Its showing me the projects content I want to show in the modal.
Something must happen in your console though. Can you see the post request being executed when you click on the link?
I did a quick test in a Starterkit and the code should actually work as it.
Oh no!! I found the issue… The projects modal was hidden and the function to show it was only placed in the click function 
Always debug properly…
Will do!!! Thank you so much for your help
