Mongo aggregate $match and $group in $lookup result - node.js

Question

I have node text
I have 3 models lead, user and company
I want to get all customers for selected company id using lead model
what I try was,
using $lookup and $group I got unique customer with details but after adding $match I got empty array
I hope someone can get my on the right track..
****This is my Aggregation code ****
const customers = await Lead.aggregate([
{
$match: { moving_company: companyId },
},
{
$group: {
_id: {
"customer": "$customer",
},
}
},
{
$lookup: {
from: "users",
localField: "_id.customer",
foreignField: "_id",
as: "myCustomResut",
},
},
]);
This is my Company model
const schemaOptions: mongoose.SchemaOptions = {
_id: true,
id: false,
timestamps: true,
skipVersioning: true,
strict: false,
toJSON: {
getters: true,
virtuals: true,
},
};
export const CompanySchema = new mongoose.Schema(
{
name: {
type: Schema.Types.String,
},
},
schemaOptions
);
const Company = mongoose.model<ICompany>("Company", CompanySchema);
export default Company;
This my lead model
const schemaOptions: mongoose.SchemaOptions = {
_id: true,
id: false,
timestamps: true,
skipVersioning: true,
strict: false,
toJSON: {
getters: true,
virtuals: true,
},
};
export const LeadSchema = new mongoose.Schema(
{
status: {
type: Schema.Types.String,
},
customer: {
type: Schema.Types.ObjectId,
ref: Customer.modelName
},
assigned_sales_agent: {
type: Schema.Types.String,
ref: Agent.modelName
},
moving_company: {
type: Schema.Types.ObjectId,
ref:Company.modelName
},
selected_categories: [
{
type: SelectedCategorySchema,
},
],
},
schemaOptions
);
const Lead = mongoose.model<ILead>("Lead", LeadSchema);
export default Lead;
This is my customer model
export const customerSchema = new mongoose.Schema(
{
address: {
type: Schema.Types.ObjectId,
ref: Addresses,
},
},
UserSchemaOptions
);
export const Customer = User.discriminator<ICustomer>(
"Customer",
customerSchema,
Role.CUSTOMER
);
export default Customer;
