Hi Rod,

Changing the level to INFO gave enough detail to workout where the error was

2021-10-13 15:31:42,119 - - ERROR [org.springframework.webflow.execution.ActionExecutionException:91] - 
org.springframework.webflow.execution.ActionExecutionException: Exception thrown executing net.shibboleth.idp.saml.saml2
.profile.impl.PopulateEncryptionParameters at 478e9a7 in state 'OutboundContextsAndSecurityParameters' of flow 'SAML2/Redir
ect/SSO' -- action execution attributes were 'map[[empty]]'
        at org.springframework.webflow.execution.ActionExecutor.execute(
Caused by: org.cryptacular.StreamException: IO error
        at org.cryptacular.util.CertUtil.readCertificate(
Caused by: Short read of DER length

Turned out to be a corrupt encryption certificate in the metadata.

Thanks for the hint.
