We just upgraded to API gateway version 11.0 in our staging environment and now we are noticing SAML assertion is getting added with some special characters due to which the related integration is not working anymore as the backend application is not recognizing that SAML response.
Release : 10.x, 11.x
The added special characters are carriage return. It is related to SANTURAIO-482 issue.
in system.properties file, restart the gateway.
