The OIG request API call returns the following error:

IDENTIFIER_NOT_FOUND

This error will arise if the requester user has not been assigned to the Okta Access Requests app.

• Okta Identity Governance

• Access Requests

When making below OIG request API call on behalf of another user <userId>:

POST /governance/api/v1/requests

with body:

{
  "requestTypeId": "<requestTypeId>",
  "subject": "<subject>",
  "requesterUserIds": [
    "<userId>"
  ]
}

and the requester user <userId> has not been assigned to the Okta Access Requests app, the call will fail with the following error:

"errorCode": "E0000001",
"errorSummary": "Api validation failed: requesterUserIds/0 <userId> not found",
"errorLink": "E0000001",
"errorCauses": [
{
"domain": "governance",
"errorSummary": "<userId> not found",
"reason": "IDENTIFIER_NOT_FOUND",
"locationType": "body",
"location": "/requesterUserIds/0"
}
],
"errorId": "<errorId>"
},

To resolve the issue, 

1. From the Admin console, navigate to Applications > Applications > Okta Access Requests.
2. Assign the user to the application.
3. Attempt to create the New Request via API again.
