the https example is not running, due to interface change?

app/Main.hs:20:31: error:
Not in scope: type constructor or class ‘Z.Credentials’
NB: the module ‘Network.Simple.TCP.TLS’ does not export ‘Credentials’.
Suggested fix:
Perhaps use one of these:
‘Z.Credential’ (imported from Network.Simple.TCP.TLS),
‘T.Credentials’ (imported from Network.TLS),
‘T.Credential’ (imported from Network.TLS)
|
20 | client :: CertificateStore -> Z.Credentials -> NS.HostName
