API request to Approve/Deny request to join a Group Hub Doesn't Seem to Work

I'm writing a component that will automatically approve a request to join a closed Group Hub.
This will be included in the relevant page quilt and is intended to replicate the functionality of legacy Groups where a group was Open but you had to explicitly join it before you saw content.
Looking at the relevant API documentation, it seems like it would be a relatively straightforward thing to implement.

The component looks like the following:

<#import "khoros-user-utils.ftl" as userUtils />

<#if user.registered >
  <#assign uid = user.id?c />
  <#assign node = coreNode.id />
  <#assign messagePostBody = {
      "type": "membership_request",
      "approve_request": true,
      "user_id": uid
  } />
  <#assign url = "/nodes/grouphub:${node}/membership_requests" />
  <#assign resp = restadmin("2.0",url,"PUT",messagePostBody) />

</#if>

 

The API always returns "Membership Request not found" even though there is definitely a membership request for the relevant user in the relevant Group Hub:

{
  "status" : "success",
  "message" : "",
  "http_code" : 200,
  "data" : {
    "type" : "membership_requests",
    "list_item_type" : "membership_request",
    "size" : 1,
    "items" : [ {
      "type" : "membership_request",
      "user" : {
        "type" : "user",
        "id" : "226",
        "href" : "/users/226",
        "view_href" : "/t5/user/viewprofilepage/user-id/226",
        "login" : "Doug"
      },
      "request_to_join_date" : "2020-09-18T00:56:56.885+02:00"
    } ]
  },
  "metadata" : { }
}

 

Is there a bug with the API call or am I calling it incorrectly?

    Hi phoneboy 

     

     

    The only difference I can see between your example and the documentation is that the docs show the body parameters wrapped in data object.  Maybe try this format?

     

    {
  "data" : {
    "type": "membership_request",
      "approve_request": true,
      "user_id": uid
   }
}

     

    You might also try the restBuilder FreeMarker method.

    Let me know if one of those options don't work and I'll keep digging.

    Tried that format, same result.
    The error returned, if it's helpful:

    {
 "status":"error",
 "message":"Membership Request not found.",
 "data": {
   "type":"error_data",
   "code":505,
   "developer_message":"",
   "more_info":""
 },
 "metadata":{}
}

     

    Making the same call using restBuilder:

      <#assign approve = restBuilder()
    .method("PUT")
    .path("/nodes/grouphub:" + node + "/membership_requests")
    .body({ "data" : {
      "type": "membership_request",
      "approve_request": "true",
      "user_id": uid
    } })
    .admin(true) />
  <#assign resp = approve.call() />

     

    I get the dreaded Freemarker error dump with this being the only potentially meaningful error:

    Caused by: freemarker.template.TemplateModelException: unexpected exception during rest call: FreemarkerRestCall{version='2.0', restCall=RestCall{path=[nodes, grouphub:myCommunity, membership_requests], action=PUT}, adminCall=true, impersonationParameterSource=null}

    On my page quilt, it says "Widget cannot be displayed."

    Well, I figured out what the issue was.
    On a lark, I tried a raw API call with curl, which actually worked:

     

    phoneboy-cli:~ $ curl -u mystageuser:mystagepass -X PUT https://mystageurl/api/2.0/nodes/grouphub:myGroupHub/membership_requests -H 'Content-Type: application/json' -H 'li-api-session-key: mysessiontoken' -d '{ "data": { "type": "membership_request", "approve_request": true, "user_id": 226 } } '

     

    That helped me figure out uid was being interpreted as a string versus a number, which is what the API expects.
    Somehow, I thought putting ?c would resolve this, but instead I need to replace  that with ?number.

    Note this still doesn't solve the issue with restBuilder, which crashes even with the above change.
    That said, I at least have a working solution now.

    I really wish the Community API gave more meaningful error messages.
    Most of the ones I've encountered have been...terribly unhelpful.
