Unable to Invoke Service AddDynamicRemoteSubscription > CS386233

Hi All,

 

I have a lot off error messages in application_log like : Unable to dispatch [ uri = /Things/PersistentSession124f3131-c19f-461d-b5ac-0bf932cadad1/Services/AddDynamicRemoteSubscription/]: Unable to Invoke Service AddDynamicRemoteSubscription on PersistentSession124f3131-c19f-461d-b5ac-0bf932cadad1 : Not authorized for ServiceInvoke on ForwardEvent in PersistentSession124f3131-c19f-461d-b5ac-0bf932cadad1

 

And this:  error executing APIRequest Message: Not authorized for ServiceInvoke on ForwardEvent in PersistentSession124f3131-c19f-461d-b5ac-0bf932cadad1, sending ERROR ResponseMessage to caller!

 

I did find the CS386233 and tried the solution , i did change the permission on User level and UserGroup level only the error messages still come in the application_log.

 

anyone got an idea how to fix this.

We use TW version 9.3.8.

 

Best regards,

Emiel

It seems to be saying that the user doesn't have permissions on: ForwardEvent not AddDynamicRemoteSubscription.

Did you set permissions on that Service/Event?

    I, too, would like to know where the ForwardEvent service is. All I've been able to find is someone saying to add collection permissions to get this to work. Personally, I think that's lazy and doesn't really solve the problem since there are unwanted security issues with that approach.

      Hi @EM_10066743 ,

      Typically, the following permissions are required for adding the dynamic subscription:

      1. The user needs to have access to invoke the ForwardEvent service on the RemoteThing instance (BrowserGateway)

      2. Property Read permission on the property being subscribed to or all properties of the thing if a property name is not supplied.

      3. Visibility permission on the publisher thing.

        Can you confirm what operations will lead to those errors?

        There are some permision management improvements since TW 8.5.

        In order to find the root cause, we need to know the exact instance version and related operations first.
