Sandbox xsi-events subscription not found

[aluxmore]

When I use the sandbox to create a subscription such as uri:

http://broadsoftsandboxxsp.cisco.com/com.broadsoft.xsi-events/v2.0/user/<<user information>>

where <<user information>> is the actual information established when I created the lab with body:

<?xml version="1.0" encoding="UTF-8"?>
<Subscription xmlns="http://schema.broadsoft.com/xsi">
    <event>Advanced Call</event>
    <expires>3600</expires>
    <httpContact>
        <uri><<my active endpoint>></uri>
    </httpContact>
    <applicationId>MyApplicationName</applicationId>
</Subscription>

(where <<my active endpoint>> is an actual uri that is publicly accessible and listening for POST requests) I get a response very much like:

<?xml version="1.0" encoding="UTF-8"?>
<Subscription xmlns="http://schema.broadsoft.com/xsi">
    <subscriptionId><<my id>></subscriptionId>
    <expires>3600</expires>
</Subscription>

Where <<my id>> is an id.  However, not only does my endpoint never register a request, but further requests to uri:

http://broadsoftsandboxxsp.cisco.com/com.broadsoft.xsi-events/v2.0/subscription/<<my id>>

give me this result:

<?xml version="1.0" encoding="UTF-8"?>
<ErrorInfo xmlns="http://schema.broadsoft.com/xsi">
    <summary>Subscription id <<my id>> not found</summary>
    <summaryEnglish>Subscription id <<my id>> not found</summaryEnglish>
    <errorCode>110862</errorCode>
</ErrorInfo>

Is this a known problem with the sandbox, or am I doing something wrong?  All requests are made with basic auth using the users' information established when the sandbox was created.

Hi. 

Looks like we're trying to achive som common goals here.

I managed to create a subscription for a user, receive the first xsi:event at the HttpContact and also successfully query the subscription endpoint. (Like you I've previously got 404 Not Found in return.) 

Problem: I only receive the initial event at the HttpContact. No further events are received at HttpContact-endpoint when I make some test-calls.

Hopefully some admin here will tell us if the system has been set up correctly and functionallity verified.

@ zowu & @skumar1 : Do you have any insight on this.

I am investigating the reported issue, will keep you posted.

[simonbrinkmann]

@skumar1I found the problem. 

The reason I was only receiving the initial request was because I had tried to add more services to the user I was subscribing to. I did this early in the process because I didn't get it to work and thought that I had to manually configure services to make call events work. 

When I re-tested with a user with default sandbox configuration I received the events.

@aluxmore : I experienced the problem with the missing subscription today because my httpcontact endpoint did not respond correctly. It seems like the subscription is immediately terminated in that case resulting in Not Found.

[aluxmore · Accepted solution]

Thanks @simonbrinkmann you put me on the right track.  It appears that the subscription doesn't work if the httpContact uri does not have a path (ie just has a host).  For instance, I can get it to work when I specify https://12345abc.ngrok.io/api as the endpoint, but not https://12345abc.ngrok.io.  Not sure if this is intended behaviour, but at any rate it works now.  Thanks.

@aluxmore : I just testet and I find the same as you. I just didn't see this because I happened to have two path segments in my httpcontact. 

It looks like Jakarta compensates for our ignorance by inserting some helpfull nulls :-) This is probably going to save me some time later when we start deploying!

If you had appended a front-slash you would have seen the SubscriptionTerminatedEvent in the ngrok-inspect or whatever tool you use for webhooks.

Suggest you mark your own reply as answer to this thread.

It's a;ways recommended to assign the required services. Additional/services may interrupt the message flows.
