Native query variable, date field filter for mongodb query

Hi, thanks so much for this great tool and it would be really great if it has more support for monogdb. so here I'm trying to use date field filter on a date field which was a result of lookup stage between two collections as shown in this mongodb query but I'm getting this error on the screenshot
I'm new to metabase and I really appreciate any help and guidance , Thank you

[{
$match: {
tierCode: 'client'
}
}, {
$lookup: {
from: 'users',
localField: 'meta.orgInfo.id',
foreignField: 'meta.orgInfo.id',
as: 'client_users'
}
}, {
$project: {
client_id: '$id',
usr_cd: '$client_users.meta.createdDate',
usr_id: '$client_users.id'
}
}, {
$unwind: {
path: '$usr_cd'
}
}, {
$unwind: {
path: '$usr_id'
}
}, {
$project: {
client_id: '$client_id',
usr_cd: '$usr_cd',
usr_id: '$usr_id'
}
}, {
$match:
{usr_cd:
{{created_date}}

}
}]

Hi @Lina
Field Filters works differently from other variables:
