Problems
When I do Fetch company and its associated users are not able to get into the below Hierarchy and also not able to get the address of them
{
"companyId": 1,
"companyName": "ABC",
"address": {},
"users": [{
"userId": 1,
"email": "sachin#gmail.com",
"address": {}
}]
}
Eror

"companyUserMappingId": 1,

"companyId": 1,
