Cosmos DB query fail if parent object is null - mongodb

Question

I am converting Mongodb to Cosmos DB without any code change. I use spring-boot-starter-data-mongo api and org.springframework.data.mongodb.core.query.Query to select only few fields in document not all fields.
Selecting _id,address.primary.email,address.primary.secondary from emp1 it works fine, if I use the same query select emp2, it fails, because emp2 doesn't have secondary address.
How to fix this issue ?
Query: { "_id" : { "$in" : ["Emp2"] } }, Fields: { "_id" :
1,"address.primary.email":1,"address.secondary.email":1},, Sort: { }
mongoTemplate.find(query,EmployeeColl.class);
[
{
"_id": "Emp1",
"name": "Name1",
"address": {
"primary": {
"email": "eamp1#gmail.com"
},
"secondary": {
"email": "emp1sec#gmail.com"
}
}
},
{
"_id": "Emp2",
"name": "Name2",
"address": {
"primary": {
"email": "emp2#gmail.com"
}
}
}
]
Exception:
UncategorizedMongoDbException: Query failed with error code 1 and error message
