AudienceRestriction' of type 'null' in assertion

[rytina]

Dear Structurizr Community,

I am using the docker image structurizr/onpremises and configured SAML-based Sign-on with an Azure Enterprise Application. With the image tag 3263 everything worked fine. When switching to the image tag 2024.01.02, I recognized that the structurizr.properties file needs to be adjusted with the structurizr.saml.metadata property instead of the saml-idp-metadata.xml file and the Reply URL in the Azure SAML Configuration has to be changed to htttps://{structurizr-url}/login/saml2/sso

But then after tying to login i get following error message:

Invalid assertion [_871cc480-624d-4ffa-8afd-1c072c934000] for SAML response [_900f060f-58cd-43d8-9bf7-357ddcaea55c]: Condition '{urn:oasis:names:tc:SAML:2.0:assertion}AudienceRestriction' of type 'null' in assertion '_871cc480-624d-4ffa-8afd-1c072c934000' was not valid.: None of the audiences within Assertion '_871cc480-624d-4ffa-8afd-1c072c934000' matched the list of valid audiances

I don't know where the audiances have to be configured properly. Could you please help me out.

Regards,
Andy

The reason for this error was an trailing space at structurizr.url inside of structurizr.properties.
It would be nice to make it more error-tolerant (by striping white spaces) Thank you.
