HTTP Error Code: 400 Message: No tenant signing key of type X509 certificate is provisioned.

After the September release if you are configuring your service namespace as per old method you might get following error:
HTTP Error Code: 400 Message: No tenant signing key of type X509 certificate is provisioned. Trace ID: 2c46fa55-8ae8-443b-9f8a-ab885593c3fb Timestamp
This is caused because your token signing certificate is not configured properly. In order for Federation Metadata to work, this signing certificate should be configured for Service Namespace.
You have to do this by selecting the value in “Used For” set to “Service namespace”. To perform this under your Service Namespace, select ‘Certificate and Keys’ and then in “Token signing Key/Certificate” under Used for select “Service namespace”. This will solve the issue.
