As mgebhard says, the error codes 50146 means "This application is either not configured with an application-specific signing key, or the key has expired or is not yet valid. Please contact the owner of the application.".
I suggest you could try to add and verify your application domain in “Custom domain names” blade of Azure AD.
Domain verification means that your domain must be accessible through the Internet and you must publish a special TXT file with the secret key on this domain, so that Azure AD can check that this domain belongs to you.
Then you should set the switch "acceptMappedClaims" to true in your app registration manifest.
More details, you could refer to below github issue:
