How can we help?

I want to retrieve the rule name which trigger my external validation, this helper is not available with any.external. I need it like of any.custom() with helpers.state.path[0]

Joi.object({
    //...
    email: Joi.string().external(uniqueRecord)
})

const uniqueRecord = async (value: any, helpers: any): Promise<any> => {
    
    //const field = "here the value will be email"
    const tenant = helpers.prefs.context.tenant;
    const collection = helpers.prefs.context.collection;

    const query = await db.query(tenant, collection)
    const isUnique = await query.find({[field]: value}).count() === 0

    if(!isUnique){
        console.warn('uniqueRecord : not unique');
        return helpers.error('any.invalid')
    } else {
        console.log('uniqueRecord : unique');
        return undefined
    }
}

I tried to use description like on doc, but I can't retrieve it on my external function.
