Hi,
Have set the logback_level in the logback.xml to even trace but there is
nothing more that came out from the error.
<!-- Log at INFO level -->
<root level="trace">
<appender-ref ref="GUAC-DEFAULT" />
</root>
Below is the whole chain of error before hitting the saml unable to load.
would that be something that would be useful ? something to do with the
REST endpoint ?
