Is it a possible to use enum as type for fields in additionalFields ?

I want to use the role field directly with my user session, I have a enum with "ADMIN" and "USER"

hmm? does this mean you want to have a role field in your user table?

Yes exactly, i'm using Prisma as database adapter and I have a role: Role? field

define addtional fields in your user config. If you need to define it as enum for type inference you can pass an array as a type. 
const auth = betterAuth({
  user: {
    role: ["ADMIN", "USER"]
  }
})
const auth = betterAuth({
  user: {
    role: ["ADMIN", "USER"]
  }
})

None of these implementations works for me, I got TS errors (even this snippet ⬆️) 
// Server Side
export const auth = betterAuth({
  user: {
    fields: {
      role: ["ADMIN", "USER"],
     // ^? error here
    },
  },
  user: {
    role: ["ADMIN", "USER"],
     // ^? error here
  },
  user: {
    additionalFields: {
      role: ["ADMIN", "USER"],
   //  ^? error here
    },
  },
})
// Server Side
export const auth = betterAuth({
  user: {
    fields: {
      role: ["ADMIN", "USER"],
     // ^? error here
    },
  },
  user: {
    role: ["ADMIN", "USER"],
     // ^? error here
  },
  user: {
    additionalFields: {
      role: ["ADMIN", "USER"],
   //  ^? error here
    },
  },
})

oh wait sorry 
const auth = betterAuth({
  user: {
    role: {
      type: ["ADMIN", "USER"]
    }
  }
})
const auth = betterAuth({
  user: {
    role: {
      type: ["ADMIN", "USER"]
    }
  }
})

No problem, but the TS error is still appearing 
 user: {
    role: {
    // ^? error here
      type: ["ADMIN", "USER"]
    }
  }
 user: {
    role: {
    // ^? error here
      type: ["ADMIN", "USER"]
    }
  }

thanks, this implementation kind of work, but the Prisma adapter creates a String[] instead of a reference to an enum.

you should this instead. It should be defined under addittional fields 
user: {
  additionalFields: {
     role: {
        type: ["ADMIN", "USER"]
      }
   }
  }
user: {
  additionalFields: {
     role: {
        type: ["ADMIN", "USER"]
      }
   }
  }
and the cli doesn't currently support generating enum values

It's working like that thanks ! (Don't know why undefined is a possible value but that's enough I think)

undefined is there cause session it self could be undefined

oh yes I see Thanks a lot for your help @bekacru @Phantom ! ✅✅✅ With Prisma generated client 
user: {
    additionalFields: {
      role: {
        type: Object.values(Role),
        default: ["USER"],
        required: true,
      },
    },
  },
user: {
    additionalFields: {
      role: {
        type: Object.values(Role),
        default: ["USER"],
        required: true,
      },
    },
  },

how do you navigate from login page ? how do you obtain the role (user or admin) using sign-in method and redirect to the appropriate page according to role? for example when i click on login page the data returned doesnt contain and role object
