List users as non admin with custom fields - google-admin-sdk

Question

As per the documentation, I should be able to get a list of users with a custom schema as long as the field in the schema has a value of ALL_DOMAIN_USERS in the readAccessType property. That is the exact set up I have in the admin console; Moreover, when I perform a get request to the schema get endpoint for the schema in question, I get confirmation that the schema fields are set to ALL_DOMAIN_USERS in the readAccessType property.
The problem is when I perform a users list request, I don't get the custom schema in the response. The request is the following:
GET /admin/directory/v1/users?customer=my_customer&projection=full&query=franc&viewType=domain_public
HTTP/1.1
Host: www.googleapis.com
Content-length: 0
Authorization: Bearer fakeTokena0AfH6SMD6jF2DwJbgiDZ
The response I get back is the following:
{
"nextPageToken": "tokenData",
"kind": "admin#directory#users",
"etag": "etagData",
"users": [
{
"externalIds": [
{
"type": "organization",
"value": "value"
}
],
"organizations": [
{
"department": "department",
"customType": "",
"name": "Name",
"title": "Title"
}
],
"kind": "admin#directory#user",
"name": {
"fullName": "Full Name",
"givenName": "Full",
"familyName": "Name"
},
"phones": [
{
"type": "work",
"value": "[phone]"
}
],
"thumbnailPhotoUrl": "https://photolinkurl",
"primaryEmail": "user#domain.com",
"relations": [
{
"type": "manager",
"value": "user#domain.com"
}
],
"emails": [
{
"primary": true,
"address": "user#domain.com"
}
],
"etag": "etagData",
"thumbnailPhotoEtag": "photoEtagData",
"id": "xxxxxxxxxxxxxxxxxx",
"addresses": [
{
"locality": "Locality",
"region": "XX",
"formatted": "999 Some St Some State 99999",
"primary": true,
"streetAddress": "999 Some St",
"postalCode": "99999",
"type": "work"
}
]
}
]
}
However, if I perform the same request with a super admin user, I get an extra property in the response:
"customSchemas": {
"Dir": {
"fieldOne": false,
"fieldTwo": "value",
"fieldThree": value
}
}
My understanding is that I should get the custom schema with a non admin user as long as the custom schema fields are set to be visible by all domain users. This is not happening. I opened a support ticket with G Suite but the guy that provided "support", send me in this direction. I believe this is a bug or maybe I overlooked something.

Answer 1

I contacted G Suite support and in fact, this issue is a domain specific problem.
It took several weeks for the issue to be addressed by the support engineers at Google but it was finally resolved. The behaviour is the intended one now.
