Hi @ilaehsa
The error itself is actually pretty clear, luckily.
It says your Specific User cannot be found. Which means 1 or 3 things
1. The user account is disabled or has been removed/deleted/removed from group/team/AAD
yeah pretty much thats it, since you are using a dynamic property, please go look at the configuration for that account wherever it is.
Because look at the error, the values are Blank (Displayname and Email) because the Claim is not valid (it is not specifying an actual user, so its not just that ther user does not exist, its tat you didnt specify one according to this)
"message": "The specified user [{\"@odata.type\":\"#Microsoft.Azure.Connectors.SharePoint.SPListExpandedUser\",\"Claims\":\"i:0#.f|membership|.---\",\"DisplayName\":\"---\",\"Email\":\"---
If you like my answer, I would really appreciate if you please Mark it as Resolved, and give it a thumbs up, so it can help others
Cheers
Thank You
