Regression: CreateLinkPostRequestBody serializes retainInheritedPermissions=false by default starting in 1.59.2

Describe the bug

Context

I was using the CreateLinkPostRequestBody to create some link to my driveItems, and it was working properly, but at some point I noticed that some of these files would not be visible to some users anymore (inherited permissions were lost).

The "bug"

Starting with msgraph-sdk-python 1.59.2, CreateLinkPostRequestBody serializes: { "retainInheritedPermissions": false, "sendNotification": false } when these properties are not explicitly set by the caller.

This changes the behavior of the createLink API. According to the Microsoft Graph documentation, retainInheritedPermissions is optional and the service default when omitted is true .

Expected behavior

I believe that the CreateLinkPostRequestBody default attribute values should follow the defaults of the createLink API.

Thus setting retainInheritedPermissions to true (or unset) for the createLink API if not provided in CreateLinkPostRequestBody.

How to reproduce

test.py

from msgraph.generated.drives.item.items.item.create_link.create_link_post_request_body import CreateLinkPostRequestBody

request_body = CreateLinkPostRequestBody(
    type="view",
    scope="organization"
)
from kiota_serialization_json.json_serialization_writer import JsonSerializationWriter
writer = JsonSerializationWriter()


request_body.serialize(writer)
print(writer.get_serialized_content().decode('utf-8'))

Results

version 1.58.0

{
"scope": "organization",
"type": "view"
}

This will let the createLink API default the retainInheritedPermissions to True.

version 1.59.2 and 1.60.0

{
"retainInheritedPermissions": false,
"scope": "organization",
"sendNotification": false,
"type": "view"
}

This will remove existing permissions.

SDK Version

1.59.2

Latest version known to work for scenario above?

1.58.0

Known Workarounds

Explicitly adding the retain_inherited_permissions = True

request_body = CreateLinkPostRequestBody(
    retain_inherited_permissions=True,
    type="view",
    scope="organization"
)

### Configuration

Ubuntu 22.04
x86_64

### Other information

_No response_

Start with the generated CreateLinkPostRequestBody entry point shown in the import path and reproduce serialization using the test.py example. Compare the output with versions 1.58.0 and 1.59.2, focusing on omitted retainInheritedPermissions and sendNotification values. Done means unset properties no longer serialize false values, allowing the createLink API defaults to apply.
