CREATE_FAILED : Flavor's local disks conflict. You need to create a bootable volume to use this flavor for your instance

Question

As I'm trying to create a stack, I get the following error :

[kypo-proxy-jump-stack]: CREATE_FAILED  Resource CREATE failed: 
Forbidden: resources.kypo-proxy-jump: Flavor's local disks conflict. 
You need to create a bootable volume to use this flavor for your instance. (HTTP 403)

I already tried to boot instance from image and attach non-bootable volume, as given in the link below : https://docs.openstack.org/ocata/user-guide/cli-nova-launch-instance-from-volume.html but it didn't work.
