We are executing the following REST API query
terra.crm6.dynamics.com/.../emails(f0f3f8c3-dcae-ec11-983f-002248936aa6)
The issue we have is that the nested expand returns no data as below:
{
"@odata.etag": "W/\"5364918\"",
"subject": "EMAIL A",
"activityid": "f0f3f8c3-dcae-ec11-983f-002248936aa6",
"email_activity_parties": [
{
"@odata.etag": "W/\"4911349\"",
"addressused": "brian.t.langdon@gmail.com",
"participationtypemask": 1,
"activitypartyid": "f2f3f8c3-dcae-ec11-983f-002248936aa6",
"partyid_contact": null,
"partyid_systemuser": null,
"activityid_email": null
},
{
"@odata.etag": "W/\"4911350\"",
"addressused": "paul.marsh@terra.com",
"participationtypemask": 2,
"activitypartyid": "f3f3f8c3-dcae-ec11-983f-002248936aa6",
"partyid_contact": null,
"partyid_systemuser": null,
"activityid_email": null
},
]
}
Does anybody have any idea why we cannot expand partyid_contact, partyid_systemuser etc?
