Need help with RESTCLIENT WebReport tag

HFCDev

I'm trying to use the [LL_REPTAG_RESTCLIENT /] tag in a webreport. Ultimately I want to use it to call custom REST endpoints in my Content Server environment but the problem I have can be reproduced with a core call. Here is my WebReport:

[LL_REPTAG_'' ASSOCACTION:CREATE SETVAR:authHeader /]

[LL_REPTAG_!authHeader ASSOCACTION:ADD:"otcsticket":[LL_REPTAG_OTCSTICKET /] SETVAR:authHeader /]

Auth Header: [LL_REPTAG_!authHeader /]<br/>

[LL_WEBREPORT_RESTCLIENT @HOST:'mtxxxxxxxxxxx.domain.ca' 

                         @PORT:80 

                         @URI:'[LL_REPTAG_URLPREFIX /]/api/v2/members/1000' 

                         @HEADER:[LL_REPTAG_!authHeader /] 

                         @METHOD:GET  

                         @TIMEOUT:10 

                         @OUTPUT:ASSOC:userInfo /]

User Info: [LL_REPTAG_!userInfo /]`

When I run this, I always get an authentication error. I tried calling the same API in Postman where I pass in an appropriate otcsticket obtained from Authentication, it just works. From within a WebReport, this doesn't seem to work. I could not find any documentation about how you would use RESTCLIENT to query Content Server so I'm not absolutely sure I have the right format for the header that needs to go into the RestClient tag. I'm also not sure of the HOST param. It's mandatory but I want to be sure that whatever I call is the same as my ticket.

Can anyone tell me how this is supposed to work for calling a local REST API from your WebReport?

I discovered that a workaround to this is you can still call a REST endpoint in Content Server from a WebReport if you use plain old Javascript. That is you write a block like this.

async function getMyData(url, otcsticket) {
   const options = {
                     method: 'GET',
                     headers: {
                        'otcsticket': otcsticket
                     }
    };
  const response = await fetch(url, options);
  const data = response.data();

  return data;
}
// this gets called when the page loads
getMyData(myUrl, "[LL_REPTAG_OTCSTICKET /]")
.then((data) ⇒ {
            // do something with data which contains the response JSON
})
.catch((error) ⇒ {
        // handle the exception
});

The only thing about this approach is that this only works for a page that can update dynamically. That is, you're not going to get the results of your query right away, meaning this is a useful technique in a WR in a widget, but not so much a good technique if you need everything at the time the page loads, and I suspect that LL_REPTAG_RESTCLIENT cannot work asynchronously (actually someone said so in another post). Actually not sure then where you could even use RESTCLIENT tag if it cannot handle async calls.
