associateEntraidObjectguidIntoOktaUd.flow (30.2 KB)
i everyone,
I ran into an issue while trying to update the Microsoft User ID (microsoftUserId) on an app assignment using Okta Workflows, following the official documentation.
Issue
When using a Compose card to build the payload like this:
{
"microsoftUserId": "ObjectID"
}
and passing that into Update Application Profile for Assigned User, the call fails with:
Api validation failed: assignment
Microsoft User ID must be a valid UUID
Even though the value being passed is a valid GUID (from Entra ID Object ID).
Root Cause
The Workflows card already provides a generated field for Microsoft User ID, so it expects a raw string value, not a JSON object.
Using a Compose card wraps/transforms the value, causing validation to fail.
Fix
Pass the Entra Object ID directly into the “Microsoft User ID” field in the card:
-
No Compose
-
No JSON wrapper
-
Just the GUID string (e.g.
33dabae1-0197-4df8-bb0c-6c19cc70b69b) -
Attached a copy of the flow.
Thank you.
Michele
