[Share-ng root endpoint]Can't update expiration date for shared project drive

[amrita-shrestha]

Describe the bug

user attempted to modify the expiration date of a shared project drive but encountered a 500 status code. However, when trying to update the expiration date with a specific role, a 200 status code was returned successfully. Therefore, the issue seems to be related to changing the expiration date alone.

Steps to reproduce

1. create project project1
2. share project project1 using POST /drives/{driveID}/root/invite with expiration date
3. update share permission expiration date using PATCH /drives/{driveID}/root/permissions/{permissionID}

curl --request PATCH 'https://localhost:9200/graph/v1beta1/drives/480b89c5-bc98-4278-a659-da42d2e92589$aa2c1f37-8aed-4ab5-a800-169fec41256e/root/permissions/u:4c510ada-c86b-4815-8820-42cdf82c3d51' \
--data '{
    "expirationDateTime":"2025-07-15T14:00:00Z"
}'
-------------------Response ----------------------
{
    "error": {
        "code": "generalException",
        "innererror": {
            "date": "2024-04-19T09:13:42Z",
            "request-id": "amrita-OptiPlex-3090/nysBpiUMXC-001893"
        },
        "message": "rpc error: code = Internal desc = runtime error: invalid memory address or nil pointer dereference"
    }
}

Expected behavior

expiration date should be able to be modified

Actual behavior

expiration date should changed if body contains role value only similar to body containing both role and expiration date

curl --location --request PATCH 'https://localhost:9200/graph/v1beta1/drives/480b89c5-bc98-4278-a659-da42d2e92589$aa2c1f37-8aed-4ab5-a800-169fec41256e/root/permissions/u:4c510ada-c86b-4815-8820-42cdf82c3d51' \
