Logical Upsert example does not work

[MB175]

https://fenos.github.io/dqlx/docs/mutations/set

The example has a dot to much and does not work since the type does not fit

data := []map[string]interface{}{
    {
        "uid": "uid(v)",
        "email": "user@company1.io",
        "name": "first name"
    },
}

userByEmailQuery := dqlx.Query(dqlx.EqFn("email", "user@company1.io")).  
    .Select(` // There shouldn't be a Dot here
        v as uid
        name
    `)

resp, err := db.Mutation().
    Query(userByEmailQuery).  // Type does not implement 'DQLizer'
    Set(data).
    Execute(ctx)
