MS Graph - Access Reviews - recurrenceType Dependency? - microsoft-graph-api

Question

I am able to create an access review using this JSON:
{
"displayName": "Test-review-2 Group Membership Review",
"startDateTime":"2020-01-15T00:00:11.111Z",
"endDateTime":"2020-04-04T00:00:11.111Z",
"reviewedEntity":
{
"id": "f4b4b660-a6c2-4b1f-bb16-75f81432a63e"
},
"reviewerType" : "entityOwners",
"businessFlowTemplateId": "6e4f3d20-c5c3-407f-9695-8460952bcc68",
"description":"Access Review for the AAD group:Test-review-2(f4b4b660-a6c2-4b1f-bb16-75f81432a63e)",
"settings":
{
"mailNotificationsEnabled":true,
"remindersEnabled": true,
"justificationRequiredOnApproval":true,
"autoReviewEnabled":false,
"activityDurationInDays":365,
"autoApplyReviewResultsEnabled":true,
"accessRecommendationsEnabled":false,
"recurrenceSettings":
{
"recurrenceType":"onetime",
"recurrenceEndType":"occurrences",
"durationInDays":7,
"recurrenceCount":3
},
"autoReviewSettings":{
"notReviewedResult":"Approve"
}
}
}
If I change the recurrenceType to "weekly", I suddenly get an error:
Unhandled exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
---> System.AggregateException: One or more errors occurred. (Message: An error has occurred.

I have looked through the documentation, and can't understand why.. Is there a dependent property I'm missing?

Answer 1

It looks like, in your example, recurrenceSettings is being passed in with the following values:
"recurrenceSettings":
{
"recurrenceType":"weekly",
"recurrenceEndType":"occurrences",
"durationInDays":7,
"recurrenceCount":3
},
"autoReviewSettings":{
"notReviewedResult":"Approve"
}
There are limits to the duration in days that one can specify for recurring reviews:
weekly -> 6
monthly -> 27
quarterly -> 80
annual -> 360
The durationInDays value that you’re passing for recurrenceType weekly is greater than the allowed maximum(6). Please try setting a value less than 7.
