Hi,
Has anybody observed that post successful ingesting the data in Customer Insights and unifying the customer. While creating the activities, we are unable to create the activities in Customer insights and it throws error, please check the screenshot below.

WebClient Version: 2022.10.4.2
API Version: 2022.10.4.18
It was working before 23 Oct 2022 as it could create the relationships if it does not exists
In case if you have observed the same and are aware about the resolution please respond on this post.
Many Thanks in advance :)
