Currently, the

@unique

or

@@unique

directives do not work with MongoDB. I thought of using JSON schema for validation / prevent duplications but that is not supported as far as I am aware unless using Realm. Has anyone figured out a workaround ?

Hey there 👋 as far as I’m aware, both should work with MongoDB. In the docs, it’s stated that they’re enforced using a unique index. What makes you think these attributes don’t work with MongoDB?

Sorry, I was using an old version of Prisma. !n update solved my problem
