Prisma user id is Int but referenced as string

When I generate the schema with Prisma the user id in user modal is from type Int. But the references of the id is defined as string.

I get the error:
Error parsing attribute "@relation": The type of the field userId in the model Session is not matching the type of the referenced field id in model User.Prisma

"@prisma/client": "^6.18.0",
"prisma": "^6.18.0",

npx @better-auth/cli generate --config ./app/utils/auth.server.ts --output ./prisma/schema.prisma

Output:
model User {
  id            Int       @id @default(autoincrement())
