ApplicationUri is empty in CreateSessionResponse

[gajanak]

hi,

i evaluate the sample server code, and don't know if it's my fault using it.

If i start the Sample Code , GetEndpoint Returns list of endpoints where ApplicationDescription is filled correct from server.conf

But if I monitor the connection with Wireshark, i noticed that in CreateSessionResponse the Endpoints contains a different ApplicationDescription where
ApplicationUri: [OpcUa Null String]

Is this i known Issue, or what I'am doing wrong ?

GetEndpointsResponse - this seems correct:

OpcUa Binary Protocol

Has anyone any Hint for me ?

This has the effect, that a opcua-client reports BadCertificateApplicationURI mismatch error ... because "" !=

Using version = "0.11.0"

UPDATE:

Short after write I found new_endpoint_description with all_fields:false will set
application_uri
product_uri
application_name
To Null..

Perhaps it would be better, to only set server_certificate to NULL how the Opcua-Spec says.... ?
