Using the Unified API call
POST https://graph.microsoft.com/{version}/{tenant}/groups('{groupId}')/events
to add calendar events to a group. I'm intermittently getting the following error:
An unexpected 'PrimitiveValue' node was found when reading from the JSON reader. A 'StartObject' node was expected.
My Json object looks to match what is provided in the online documentation. Has anyone seen this error and, if so, do you have a resolution?
