I am going to write a Cards model for payments. However, I am going to index and make unique only verified cards. Cards model has attribute:status. It can be verified or unverified. First, I wrote partialFilterExpression using typegoose. However it is not indexing only verified values

@index(
    {
        number: 1
    },
    {
        unique: true,
        name: 'number',
        background: true,
        partialFilterExpression:{
            is_deleted:false,
            completely_deleted:false,
            status:"verified"
        }
    }
)
