I trying to use Azure AD B2C to authenticate with ShinyProxy and I believe this is possible. I have tested by Azure AD B2C set via https://jwt.ms/ and another application so I think my issue does not lie on the Azure AD B2C side

Given my lack of familiarity with springframework or Spring Boot, I would appreciate confirmation, to the extent that it is possible, that the error suggests a problem either with shinyproxy/springframework or an incompatibility between shinyproxy and Azure AD B2C. I am trying to determine if the issue lies with the configuration of the Azure AD B2C tenant or a problem within the application.yml file.
If anyone has experience in this area and could provide suggestions for a potential workaround, it would be greatly appreciated.
