I'm creating a new project using Prisma 1.7.4, did a

prisma init hello-world

and deployed to stage

dev

to server

prisma-eu1

. Now I've run

prisma playground

and it's responding with an error message:

Project not found: 'public-cottonvoice-242~undefined@dev

. Any idea? Update: I can see an

undefined

in the URL, so might be a bug getting the project name...
