Hello Amit,
The error tells us that user creation has been denied, so perhaps you require customization of Okta’s predefined registration workflow to enable this use case. So ensure that the custom attribute you are trying to push has been set up in the Self-Registration settings on your admin dashboard.
I will update you with more insight once I'm able to reproduce this error.
Any update on this topic? Just got the same error message when trying to perform SSR with custom attributes.
